There was a guy at my company who would casually jerk off in the bathroom stall about 2-3 times a week. Other guys would hear him while they were taking a piss and call him out on it. Management called him in for a meeting and he denied it of course so it was a rough situation to deal with. Eventually word spread so people started giving him weird looks and talking behind his back. He got the message that everyone hated him and thought he was a freak so he quit. So far he hasn't come back and sprayed the office with bullets so we have that going for us, which is nice.
