crackhead o'clock

Used to describe an hour so late or so early as to be almost painful, usually between the hours of 2am to 5am. Also used to denote a time where looking at your watch will be of no value, because it's just that late or early.

Betty: Damn, what time is it?
Hortense: It's crackhead o'clock, that's what it is!
