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?"
