A couple of other good ones to know:

"casus belli" = lit. "case of war" or the list of threats and complaints that are used to justify warfare.

"res ipsa loquiter" = lit. "the thing itself speaks" or it speaks for itself. Often used to illustrate, in legal terms, that a wrong has been committed by virtue of the fact that damage has been done.

Hoo hah, I'm predicting this will be the new deep-fried snack of the season at the souther state fairs this coming fall :)
