What Is Love was released in 1993 by Haddaway, a Trinidadian-German singer, and became a major Eurodance hit across Europe and the United States. Its second life came through Saturday Night Live's Roxbury Guys sketches and the 1998 film A Night at the Roxbury, where characters bobbed their heads in unison to the track in clubs and cars. That visual gag carried into early internet videos and modern edits, so the chorus alone now signals cheesy romance, awkward club confidence, and perfectly timed head-bobbing without needing the full song.
