When you are taking a shit and you either twitter or facebook while in progress of laying it down. The " tw" part is twitter. The " oo" part is for poop. The "ok" part is facebook.
You might be curious what someone is posting on facebook or twitter and you login while you are taking a shit then that is when you have been twooking.
