The Urban Shower is an expansion of the Hole In One.

One inserts their own penis into their ass hole (The Hole in One). Then they proceed to piss in their own ass. Finally they finish it off by blasting their piss onto their partner. Thus the urban shower.
"Mmm that Urban Shower you gave me last night was so warm and had just the right amount of fecal matter."
