The hook comes from television advertising for Reese's Puffs, the peanut butter and chocolate cereal inspired by Reese's Peanut Butter Cups. Its rap style jingle repeated the product name in a call and response chant designed to stick with younger viewers. Clips of the advert were later ripped, trimmed and shared on meme pages and soundboards, where the shortest section became a standalone audio. It remains popular because the chant is recognisable in under two seconds and works as an instant reference to cereal, snacks and childhood adverts.
