A time so late in the night where everything is funny to you and your friends. Usually achieved after being awake for 20 or more hours. Similar to being high, even the least funny things appear hilarious.
"Knock knock."
"Who's there?"
"You're gay."
"Hahahahahahaha! That wasn't even funny... it must be silly o'clock."
