The Clothes Hanger is the act of waking up from a long, usually drunken filled, night bare ass naked. On your trip to the bathroom, or wherever else in the house, you drape your boxers over your morning wood, using it as a clothes hanger. It is an excellent way to show your room mates that you got drunk and got some the night before.
Man 1: "So there I was sittin on the couch, and Ricky walks in and gives me a clothes hanger!"
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.
This action is often made more convincing by wiggling the eyebrows or opening the mouth, to pretend you're trying to get a Snapchat filter to work.
