The act of tweeting whilst going #2.
"That chick in the last stall is twooping".
The art of Tweeting while Pooping via any mobile device while in the bathroom.
DUDE: (Knocking madly at door): "Hey dude I need to use the Bathroom, it's an emergency!"
OTHER DUDE: "I'm almost done Twooping, it's this damn Spell Check holding me up!"
