I used to work with a guy who called certain girls "Butter Faces." As I'd never heard of such a thing, I asked what exactly that meant. His response? When everything "but her" face is banging. Um, OK. That being said, the best example of this in male form would have to be Michael Phelps. Bless his butter face heart. Or would that be buthis face? Well, now that doesn't even make sense. Nevermind. Just don't look directly at his face and you'll be fine.
