Defecatorium

[jack]

Given the utter morass of terms for rooms with toilets in, that are to a greater or lesser extent ambiguous, euphemistic, regional, slangy, crude, or all of the above, and the guarantee that if you accidentally use one that is appropriate for another subgroup it will not be understood, take people aback, or lead them into sarcasm at your expense, is it time to officially condone "defecatorium"?
