The phrase comes from informal American slang, where jit is used for a young person and trippin describes acting irrationally or overreacting, and the clip packages that attitude into a single quick reaction. Its exact original recording is not widely documented, which is typical for short meme audio that spreads through reposts, edits and reaction videos rather than a single film or show. Like the Bruh meme, it survives because the wording is instantly recognisable and easy to drop over almost any unbelievable moment, from gaming fails to everyday arguments captured on camera.
