When a hairy man decides to let loose on a Friday happy hour, letting his chest hair out in public so the bitches come flocking. The primary goal of this move is to get laid. He's kept it hidden all week but when work ends on Friday, it's Chest Hair Friday!
You see your buddy at the bar on a Friday night, chest hair out in the open, and he's talking to a girl. You come over and say, "it's Chest Hair Friday!"
