figgin

From Terry Pratchett's "Discworld". It can be defined as 'a small short-crust pasty containing raisins'. But considering that 99.99% of the population dont know this, it can mean almost anyhting!

mmm, that was a nice figgin

If you touch my computer, I'll rip out your figgin and shove it where the sun don't shine!

buf

Means "Big Ugly Fella" in its politest form.

"Hey, did you see that guy over there? Now there's a BUF if i ever saw one"
