Awesome O'clock is every hour of the day, when you don't have the time.
'Hey man, what's te time?'
The hour, usually late at night, where everything is funny and all ideas are good. Can be induced with controlled substances.
Bob: "Hey guys, what if I dressed up as Batman and went out at night to scare people? Wouldn't that be sweet?"
Everyone: "Yep, Bob's definitely hit awesome o'clock. Go to bed, Bob."
