Wasted

Wasted is the term used for when a player is severely injured and collapses in a Grand Theft Auto game by losing all of their health. In Grand Theft Auto IV and its episodes, the term Wasted is not used, but the same effect takes place.

Causes
There are many ways a protagonist can be wasted. The most common examples include being shot at until the protagonist's health is depleted, being injured in explosions, or drowning. Since Grand Theft Auto: San Andreas, the player will die if they fall from a great height. In Grand Theft Auto V, stalking another protagonist may anger them and they will retaliate by punching the player in the temple, instantly killing them.

Knocked Out
Knocked Out is a unique Wasted screen exclusive to the Sumo Adversary Mode, and the Most Wanted VIP challenge, part of Organizations. Once the player is knocked off the area (Sumo), or is killed by the police (Most Wanted), they will die with a "Knocked Out" text instead of "Wasted".

Effects
Being wasted in the 3D Universe while in a mission will result in immediate mission failure, and the player will respawn at the nearest hospital. They will be stripped of their weapons and be charged $100 ($1,000 in Grand Theft Auto III). There are some exceptions however:
 * In Grand Theft Auto: San Andreas, if Carl is dating nurse Katie Zhan, he will be able to keep his weapons upon death (this was fixed in the sixth and seventh-gen consoles, allowing Carl to keep his weapons upon death).
 * In Grand Theft Auto: Vice City Stories, the player can keep their weapons by paying a bribe of $2,000 to the hospital staff.
 * In the mobile versions of the game, the player will automatically keep all of their weapons.

In Grand Theft Auto IV, the player is fined 10% of their money (up to a maximum of $10,000) but gets to keep their weapons. In Grand Theft Auto V, the player is fined 5% of their money (up to a maximum of $5,000), but keeps their weapons too.

In Grand Theft Auto V, getting wasted on a mission gives the player the option to retry from a certain checkpoint, though some Gold medal objectives (such as time or accuracy) will be disabled, preventing 100% completion. If the player declines the option to retry, they will respawn outside the nearest hospital and lose $5,000.

In Grand Theft Auto Online if a player is killed by another player, some of their money will be dropped and can be stolen by other players if the killed player has not yet deposited their money to their Maze Bank account. Furthermore, if the player is killed by cops and their Personal Vehicle is parked nearby, it will be impounded at the LSPD Auto Impound.

Obliterated
This is another unique Wasted screen, similar to the Knocked Out screen in the Sumo Adversary mode. The Obliterated screen only appears in GTA Online and occurs whenever the player is killed by another player using the Orbital Cannon.

Trivia

 * Wasted is a term most often used for being highly intoxicated from the use of alcohol or drugs. It is also a slang word for murdered which is the reason why this message appears if a player dies on any Grand Theft Auto games except GTA IV and its episodes. This is another easter egg.
 * The term is known as "You're brown bread" in GTA London 1969 and 1961, which is Cockney rhyming slang for "you're dead".
 * In the Gameboy Color version of GTA 2, a term "Killed" is used rather than "Wasted" in the PS1, PC and Dreamcast versions.
 * In GTA 2 a special term "toasted" is used to indicate, that the player has died due to catching on fire (particularly by the effects of Flamethrower), or "shocking" to indicate, that the player has died by electricity – by walking too long on electrified rails. Maybe even by being hit by ElectroGun or ElectroFingers, but no NPC will ever use it against the player. The results are, however, perfectly the same as if they were wasted in any other way.
 * In all GTA games, a pool of blood will most likely appear under the player (with a few exceptions like the flames in GTA IV; sometimes does not happen in GTA SA).
 * In Grand Theft Auto III and Grand Theft Auto: Vice City, when the player is wasted during a mission, the word "Wasted!" will still appear on the bottom right, while also displaying Mission Failed! in the middle.
 * In Grand Theft Auto: San Andreas, when Carl fails some missions by dying, the "Mission Failed" sign will appear first and then the word "Wasted" shows up, which is somewhat strange. This also happens in the same way as Busted.
 * In GTA IV and its episodes, the term "Wasted" never appears in the screen. Instead, the screen turns grey, everything moves in slow motion, and the player is transported to the nearest hospital. However, if they die in a certain way, (the player's body is still falling, etc.) the game will continue showing the slow-mo scene until they press the continue button, which skips the scene. Skipping with the button also works when the player simply doesn't want to watch the whole "blackout". This is the only game not to have the words "Busted" and "Wasted".
 * In Grand Theft Auto: Chinatown Wars, the words "Wasted" and "Busted" have returned for the first time. An ambulance siren will be heard lighting up if Huang is "wasted".
 * The words "Wasted" and "Busted" have returned in Grand Theft Auto V (for the second time), albeit darker in tone. The screen flashes and a sound effect reminiscent of a steel rod being struck right as the words appear (albeit with minor visual differences and missing steel rod sound in the enhanced version).
 * In GTA V, when the player dies during a mission, the term Wasted isn't used, but instead it'll show "Trevor died" ("T died" in the Prologue), "Michael died" ("M died" in the Prologue), or "Franklin died" as a failure reason. (along with the "Mission Failed" message, as if it was the normal mission failure).
 * Trevor Philips' Special Ability will avoid most of the damage, including some lethal forms, like being shot by the Rhino and other explosions.
 * In GTA Online, there are different reasons appear under the "WASTED" sign, including the player committed suicide, got run over by another player's car, shot from another player's sniper rifle, caught in a man-made explosion, hit by the blade of another player's controlling helicopter, and so on.
 * Strangely enough, sometimes if the player dies in a way that happens out of the player's mind (etc. Falling over from a great height without/with a not-in-use parachute), the game occasionally still states that the player "committed suicide". This is probably an oversight from the game developers or a glitch. This situation even happens in the enhanced version, and it is one of the handful situation that doesn't get fixed by the official.
 * If the player dies in a certain way (etc. Killed by any member of law enforcement or NPCs), there will be only a WASTED sign shown up, with the left-bottom of the screen says the player died.
 * When the player gets a cutscene that a plane is destroyed during the mission Stowaway in GTA San Andreas, the same case as GTA IV will happen but without the slow motion during the wasted scene.
 * When the health cheat is entered if a "Wasted" text appears on all 3D Universe games, their health will recover but not revive on a location from where they died. It was programmed to do so because when the player was wasted, they die and not get up/regain control and will respawn to the nearest hospital.
 * Also in 3D Universe games, if the player types a health cheat when protagonist's health is depleted while the protagonist is still in his death animation (before the text "Wasted" is displayed), the health is recovered. But, after the death animation, the protagonist is still wasted and the health bar is instantly depleted. An example of this is when the player has a jetpack in GTA San Andreas and their health becomes empty, it decreases its height. A said cheat can still be entered by the player when this happens but once the jetpack is dismounted, he/she will die.
 * The camera is the same as being busted when a player is killed by any member of law enforcement in GTA Vice City.
 * Additionally, they will still point their weapons at the player even though he/she is dead. This is also the same fashion as GTA III when the above situation happens.
 * In GTA San Andreas, they will stop shooting once the player is dead regardless if a member of law enforcement killed him or not.
 * In GTA San Andreas, when one types the suicide cheat while a barber cuts Carl's hair, he will die on a left side of the chair, with a pedestrian disappearing and at the same time, the text "Wasted" is displayed.
 * Also, dying before entering a closet on all clothes stores will make a door that Carl enters disappear and a said text will appear.
 * The camera angle while entering a closet and cutting the player's hair, however, will still play instead of panning aerially.
