"What Is Love" is a 1993 eurodance song by Haddaway. Beyond radio success, it became strongly linked with the head-bobbing comedy bit from Saturday Night Live and later A Night at the Roxbury, which helped turn it into a long-running internet joke. Loud edits of the track stay popular because the opening groove and chorus are instantly familiar, making them useful for fast comedic contrast, retro dance references and deliberately overdramatic meme timing.
