What Is Love is a 1993 Eurodance hit by Haddaway that became a lasting internet favourite long after its chart run, thanks to its instantly catchy chorus and dancefloor energy. On TikTok, the track is constantly reused for shopping, haul and comedy edits, with Shopee-themed versions pairing the song with parcels, discounts and delivery clips. That mix of nostalgia and a familiar shopping platform keeps it circulating, because viewers recognise the tune in seconds and expect something fun, exaggerated or surprising to follow.
