When, usually at the bar or a party, a guy (your buddy, unless your a total dick) goes for a
broad, but you call out something that
won't give him a chance. It's usually about an STD or him having a wife.
The opposite of being a
wingman
"The Gil sewered seabass so bad at the bar last
night!"
"I just fuckin', sewered the
bastard when he went to pork my
broad."
(At the bar) "Hey BUDDY? Have ya told her about your HIV?"
