An activity performed by a male in a public place or gathering, usually a party, where a portion of the scrotum with one or more testicle or ball is fully exposed while the rest of the cockandballs is obscured. frequently this display will continue as the ball-walker mingles hither and thither dodging the occasional outbreak of shock, dismay, awe and eventually laughter creating a sort of sociological wave affect through the gathering.
"...So I was at this party with Tony (Millionaire) in L.A. and i started doing the ball-walk. one person across the room would notice and point excitedly and i'd duck behind some people and go somewhere else until someone else reacted..."
hanging your testicles out of your zipper and walking through a crowded area. commonly done at a bar after a heavy night of drinking and striking out with the ladies, a guy will decide he might as well go "ball walking". very fun to see people's faces when they catch a glimpse of your sack haning out.
