Tub Nubbin

When a paraplegic man has to use the bathroom at a stadium with a trough urinal. They wheel in and jump up placing their nubs to the edge of the trough and lean over placing a hand on the wall for balance.

Person 1: Dude did you hear what happened when TJ cut in front of that wheelchair guy in line for the bathroom at the Lions game?

Person 2: No what happened?

Person 1: Guy punched him in the back of the head and rolled right over him on his way to the urinal.

Person 2: Wait how does a wheelchair guy use a urinal?

Person 1: Come on man... you never heard of tub nubbin?

Person 2: Oh yeah tub nubbin I've heard of that!

Person 2: I bet TJ wishes he never crossed that tub nubbin some bitch.

Person 1: You can say that again!
