Boosty Stuff is a slang name for the drug cocaine in its powder form, ready for use. The term originates as a little known parody of the children's video game Cars, in which vehicles accelerate rapidly for a short period of time by consuming 'Boost Juice'. The identification by Larry the Cable Guy marking the substance as 'Boosty Stuff' in the game became known as a reference to high grade, ready to use cocaine by unknown sources.
Jim went to the crack dealer to get some boosty stuff. Jane just railed a line of boosty stuff. Don't forget your boosty stuff!
