Answer 1

The phrase "when monkeys fly out of my butt" is a humorous expression used to convey extreme skepticism or disbelief about something happening. The origin of this phrase is unclear, but it likely emerged from the absurdity and impossibility of monkeys flying out of someone's posterior. It is a colloquial and informal way of expressing doubt or incredulity.

Answer 2

It would typically be used as a sarcastic response to a statement regarding the likelihood of an event occurring - similar to "when pigs fly" or "when hell freezes over." In other words, the odds of the subject event ever happening are about as good as monkeys flying out of someone's butt. See Wayne's World. For example, my wife says "I think I will stop spending so much money" and I say "Yeah, and monkeys might fly out of my butt" - meaning, no way, no how is she going to stop spending so much money.
