For some reason, the phrase "put on your rape face" just magically materialized in my head. I've never seen it anywhere, but according to Google, I'm not the first to think of it. Let's just say I am. Examples:
Guy 1: Hey, bro, big party at Pi Phi tonight. Put on your rape face.
Girl 1 (on phone): The party was lame, I'm walking home alone.
Girl 2 (on phone): Uh-oh, better put on your rape face.
So. . . have fun with that.
