What is Toilet Gamer?
A person who sits on the toilet for an inordinate length of time because they're playing a game on their cell phone.
Sis: Damnit Tommy, get outta there! I need to take a shower!
Bro: Calm down, I'm almost done (click, click, click, click).
Sis: I hear that d-pad! Get your ass off the Can, you toilet gamer!
