Roadhouse
A Roadhouse is when you take a two shits in one trip to the bathroom, but in two sittings. The named is derived from the bar in the movie Roadhouse called "The Double Deuce". Its when you go to the bathroom sit on the toilet, take a shit, wipe, get up, pull your pants up, wash your hands, and just before you leave the bathroom you realize you are not done shitting. Now you have to sit back on the toilet for a 2nd shit(double deuce) or a Roadhouse.
Bill: What took you so long? You were in the bathroom for REALLY long time.
Dave: I would have been done sooner, but I had to shit twice.
Bill: Oh man, a Roadhouse. That happened to me last week after that Jalapeno eating contest.
