The "What is love? Baby dont hurt me" meme is a series of memes on TikTok that feature video clips of American bodybuilder Mike OHearn. The meme started to spread in March 2023 as TikTokers attached absurd captions to videos of OHearn. The meme is based on the song "What is Love" by Haddaway, which was released in 1993 and became popularized by the movie "A Night at the Roxbury". The meme is often used to express feelings of confusion or frustration in a humorous way.
