When someone farts into the intake of a CPAP machine while it's user is sleeping. There's no escape.
Similar to a Dutch Oven, but the victims of a German Shower can only be on CPAP.

The act of defecating a violent stream of diarrhea onto the head/face of another or oneself*.

The german showerer's anus plays the part of the shower faucet while the showeree enjoys** the hot fecal material enrobing his/her visage.

*see tub girl

**It is quite often the showeree does not in fact enjoy this.
"One day I consumed 3 gallons of spicey chili and went and annihilated my girlfriend's face with a violent torrent of jalapeno pepper laced excrement. She quite enjoyed the German shower but the jalapeno peppers-not so much."
