No single film, song or show is documented as the source for this clip, so its history is really about internet slang spreading together. Sussy grew out of Among Us slang for acting suspicious, while rizz became Gen Z shorthand for romantic charm during the early TikTok era. Put together with boy69, the phrase works as a ready made meme label rather than a quote with a canon origin. It circulated on soundboards and short form video as a reusable reaction, surviving because the joke lands even without any context.
