What Is Love was released by Eurodance artist Haddaway in 1993 and became a worldwide dance hit, later gaining new life through the head-bobbing car scene in the 1998 film A Night at the Roxbury. That scene turned the chorus into lasting pop-culture shorthand for awkward dancing and nightlife, and it has since been reused constantly in memes, remixes and short-form videos. Its simple hook and instantly familiar beat keep it easy to recognise across generations.
