The act of taking a nut connected to a bolt, putting it in your butt hole and then taking a wrench and twisting the nut around while the bolt is deep inside. This can be done on oneself, or two people can partake in the activity with one twisting the nut and the other enjoying it.
Me and my girlfriend tried the Urban Plumber for the first time last night, it was going great until she said it was my turn. So I pulled the bolt out of my ass and she put it in hers.
