The 'What Is Love' head-bobbing meme originates from the 1998 cult classic comedy film 'A Night at the Roxbury,' which was adapted from a recurring 'Saturday Night Live' sketch. The scene features the dim-witted but lovable Butabi brothers, Steve (played by Will Ferrell) and Doug (played by Chris Kattan), wearing their signature shiny polyester suits and aggressively nodding their heads in unison to the euro-dance hit 'What is Love' by Haddaway. The characters are portrayed as socially oblivious, overly confident wannabe club-goers looking for the next big party while driving in their car. In the digital age, this clip became a cornerstone of internet culture, often used to represent collective enthusiasm, 'vibing' with friends, or being hopelessly out of touch with one's surroundings. It perfectly captures the feeling of forced coolness and the hilarity of two people being perfectly in sync for the wrong reasons. Common uses include scenarios where a group is excited about a niche topic or arriving at an event with unearned confidence. Example caption ideas include: 'Me and the boys heading to the weekend,' 'When that one specific part of the song hits,' and 'Arriving at the party where we don't know anyone.'
