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!"
Man 2: "Nice! That dude's such a character!"
