The exact origin of this French phrase is not widely documented, and it circulates mainly as a short reaction clip shared in memes and messaging chats. Its humour comes from the repetition and the playful escalation from sa biche to sa sur biche, which listeners recognise even without a clear original video or show. Because the line is short, rhythmic and easy to repeat, creators reuse it as a standalone punchline, a comment on a screenshot, or a sound for duets and stitches. Its continued use depends on that shared recognition rather than a single viral moment.
