When a man strips naked, places a sock over his cock and balls and walks around in the presence of others. Usually performed at parties by intoxicated individuals for shock value and laughs. Individuals performing "Sock Man" frequently have their clothes stolen while in the act, or are forcefully removed from the party into the street.
Did you see Sock Man at the party last night? We stole his clothes, threw him out in the street and locked the door. We found him alseep in the alley this morning under a welcome mat.
