Newnham

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!
