The Car Salesman Slaps Roof of Car meme originated from a 2014 tweet describing a humorous interaction between a car dealer and a potential buyer. The visual template features an illustration of a salesman slapping the roof of a blue car while boasting about how many items it can fit inside. It gained massive popularity in 2018 on platforms like Reddit and Twitter, evolving into a versatile snowclone where the salesman pitches exaggerated or absurd capacities for anything from computer hardware to abstract concepts. It is widely used to highlight the excessive or unexpected contents of a specific object or idea.
