What Is Love was released by Trinidadian-German singer Haddaway in 1993 and became a global Eurodance hit, later gaining a second life through its famous use in the 1998 film A Night at the Roxbury. The song's instantly familiar chorus made it a staple of clubs, radio, and party playlists before short clips spread across video platforms and meme edits. Today the hook is used less as a full song and more as shorthand for romance, confidence, and nineties nostalgia, instantly signalling the joke even when listeners hear only a few notes.
