The 'What is Love' meme, often referred to as the 'Roxbury Guys' meme, originated from a recurring Saturday Night Live sketch featuring Chris Kattan and Will Ferrell as the Butabi brothers. The sketch became a cultural phenomenon when Jim Carrey joined them, resulting in the iconic synchronized head-bobbing scene to Haddaway's 1993 hit song. While the sketch eventually led to the 1998 film 'A Night at the Roxbury,' the meme took on a new life on the internet as a GIF and video template. It is widely used to represent infectious energy, awkward confidence, or simply to accompany any catchy beat, making it one of the most enduring nostalgic artifacts of 90s pop culture.
