2.
The act of brushing (flossing, mouth washing etc.) while taking a fat shit. Most often occurs on mornings where one wakes up late and is in a hurry to exit the house for work/school.
Guy 1: Dude you're late, what took you so long?

Guy 2: Sorry man, I woke up late. I had to take my usual morning dump but I also had to brush my teeth and I didn't know which I would have time for so I utilized the Dentist Chair

Guy 1: You're a genius.
