Humourous term for the restroom (or "WC" in Europe). It gives the user an air of vain intelligence and sophistication to apparently use a Latin term when, in reality, the user is probably too stupid to even know Pig Latin. See also "Leakatorium" and "poopalorium"
Damn, that quart of beer went right through me. Gentlemen, please excuse me. Frank, where's your pissalorium?
