jack-off-off
A dirty contest between guys to see who can blow their load the biggest and messiest, like a sperm explosion.
Jack-off-off started when four guys in the bathroom tried to see who could cum the loudest.
At the bar, Jack-off-off broke out when a guy yelled, 'I'm gonna beat your load, you ugly prick!'
In the gym, a group of guys turned the treadmill into a Jack-off-off battle, and it was glorious chaos.
