What Is Love was released by Trinidadian-German singer Haddaway in 1993 and became a huge eurodance hit across Europe and the United States. Its second life came through the Roxbury Guys sketches on Saturday Night Live, where performers including guest host Jim Carrey bobbed their heads in unison to the track in a car. That image became a widely shared GIF and reaction meme. Streamers later adopted the pairing as a subscription alert on platforms like DLive, where the instantly familiar dance cue marks a new supporter without needing any spoken announcement.
