The Pirate was recently in a meeting where one of the attendees (a large man) tipped his chair back and began absently massaging his breast. The Pirate is fairly certain he didn't realize he was doing it, and that he would be embarrassed if it were pointed out to him. But at the time, it was just screamingly funny.
Not five minutes ago, I was walking down the hall at work and passed a male co-worker doing the same thing - just walking down the hall, massaging one of his breasts.
CUT IT OUT. I mean it. It's disturbing. If I were to manhandle one of my erogenous zones during a meeting, it's a pretty sure bet that meeting would go to hell nigh instantly.
