Originally released in 1993 by Haddaway, What Is Love became a defining eurodance hit and later gained a second life through the Saturday Night Live Roxbury Guys sketches and the 1998 film A Night at the Roxbury, where characters bobbed their heads to its beat. The song's simple, repetitive chorus made it easy to reuse online, and it has since become shorthand in memes and short videos for sudden infatuation, dramatic entrances and tongue-in-cheek romance.
