The clip comes from Ace Ventura: Pet Detective, the 1994 comedy that made Jim Carrey a star with his rubber-faced performance as the eccentric animal detective. His short sarcastic laugh became a reusable reaction separate from the film, spreading through soundboards, edits, and meme videos where a fake laugh says more than words. It sits alongside other cartoonish reaction laughs like the Woody Woodpecker Laugh, but Carrey's clipped delivery and smug timing keep it tied specifically to mocking someone who thinks they were clever.
