Feeling a large number 2 Wayne squattled to the bathroom only to leave a number 0.

To sneak off to the bathroom pretending to relieve yourself, but instead, using the private time to send text messages to your secret lover on your cell phone.
I stepped away from dinner with the family to take a Number 0. My wife never suspected a thing.
