Rufus jit trippin circulates as a user-generated meme clip rather than a track with a documented original release, so its first video is hard to pin down from the sound alone. The phrase draws on slang in which jit means a young person and trippin describes acting irrationally or overreacting, giving the line a roasting quality. That combination has helped it travel through reaction edits, gaming clips and short videos, where a brief, quotable callout is more useful than a longer joke. It remains in use because the wording is simple, repeatable and easy to drop over any over-the-top moment.
