It is similar to just shitting on someone, but it has to be diarrhea, otherwise it is not a rusty shower. One can do this on any part of a person's body, but its funnier if you start on the top of the head, like an actual shower head.
Larry was so drunk that he gave his dog a rusty shower and now his dog is always skiddish around him. It's sad really.
