Slipping her a length

To have consenting sexual intercourse with a woman, to penetrate the vagina with the penis.

"Did you see Glenn Beck interviewing Quitter Palin on Faux the other day?"

"Yeah, he was a complete and utter quittergazer, I've never seen anything like it. It was almost as if he thought she made sense. He was just staring into her eyes as if he was caught in some kind of spell.

I honestly thought he was going to pull down his trousers and try slipping her a length."
