Newnham; When you are hooking up with a girl, while you are going down on her, you stick one, or preferably two fingers in her anus. You then proceed to stick those same fingers in her mouth for a period of no less than 5 seconds.
I was hooking up with this girl the other day and she was pissing me off so I Newnhamed her.

Get the Newnham mug.
When a member of your social group either;

- Commits to a social event and pulls out last minute with a large list of poor excuses.
- Snakes off during prime time boozing hours without a hint of a goodbye.
Friend 1 - Does George want a beer? Its my round.
Friend 2 - George isn't here mate, he's pulled a Newnham.
Friend 1 - Man that guy is f*cking wet!
