(1) Is 炒饭 really used as slang for "having sex"?
(2) If so, any ideas on how it came to be? (I totally do NOT associate fried rice with having sex. O_O)
(3) Is 炒冷饭 a variation of that phrase or does it mean something COMPLETELY different?
Sorry for the rather weird nature of my question, but my friend and I would really like to know the answer. :p
