Wrong hole, dumbshit!
What the girl who you're having sex with might say if you stick your penis into some part of her body where it doesn't feel good for her at all.
Oww! Wrong hole, dumbshit! Don't you ever try screwing me in my belly button! Now do me right. *guy sticks his penis into one of the girl's two crotch ends* Ahhh, now that's much better.
