O'clock
The time you go do your business. It's like your body says 'you've had enough coffee. Go drop a deuce.' It happens after lunch, after coffee, and after dinner. It's your body’s way of saying 'I'm not done yet.'
'I had to drop a deuce at 10 o'clock. My coffee was still hot.'
'He dropped a deuce at 3 o'clock. He didn't even eat lunch.'
'She dropped a deuce at 7 o'clock. It was a miracle.'
