Me when your girl is a phrase used to interrupt another persons sentence, specifically when they make a mistake. Most often used when someone stutters, but can also be used when someone corrects themselves, or if somebody says something wrong moultiple times without correcting themselves.

Often times, the phare itself is intentionally stuttered to increase the amount of embarrasment that the person who is interrupted feels.
