facile
Facile is short for facilities, and it’s just a fancy way to say 'bathroom' when you're too lazy to say it properly.
'Hey, is there a facile nearby? I need to pee.', @peeurgent
'I asked for a facile and got a door that didn’t open.', @brokenfacile
'I called it a facile and it turned out to be a janitor’s closet.', @notafacile
