She is one nasty bitch she likes it when you put your cock in her sewer. Old Betty is so nasty she will stick her tounge up your sewer hole after she gives you a blow job.

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 Gil sewered seabass so bad at the bar last night!"

(At the bar) "Hey BUDDY? Have ya told her about your HIV?"
