Chuckup is a business featured in Grand Theft Auto: San Andreas.
It has a warehouse located in the LVA Freight Depot in Las Venturas, and also sponsors Hotring Racers. The logo resembles the logos of the CSK Auto family of auto parts stores. The name parodies one of these stores, Schucks Auto Supply, although because of the game's setting, it is probably based on CSK Auto's western US stores, Kragen Auto Parts. Although, in 1992, real life store Kragen had a slightly different logo. Chuckup means an event in which one or many fails or mess up in a moment of opportunity, and they are ridiculed by peers.
