That monkeyhumper just doesn't know when to quit humping, does he? When they bleed you just have to give up.
when you're holding up your phone and making faces at it, as though you are taking a selfie, but you're really taking a picture of the person across from you or the wall or anything else that seems interesting but you don't want to be caught dead taking a picture of.
