What Is Love was released by Haddaway in 1993 and became a defining Eurodance hit of the decade, later reaching a new audience through its use in the 1998 film A Night at the Roxbury and its famous head-bobbing dance scene. The chorus lived on through internet memes, compilations and short-form video, where creators reused its instantly familiar hook for dance challenges and ironic edits. Its simple question and driving beat keep it instantly recognisable across generations, which explains why it still appears in TikTok trends today.
