When someone goes to the bathroom and leaves the door open because they have little time before they shit/pee themselves.

It's called that way because the colosseum has no doors.
Dude 1: Last night I really had to go. I was about to shit my self so I did a Colosseum Job.

Dude 2: Ew, get away from me you sick bastard.
