shower pudding 

Created when indulging in a shower wank. When the hot water combines with one's seminal fluids and lube of choice, the sperm clumps and solidifies into sticky, semi-solid, gelatinous material which attaches to said individual's pubic hair and never truly goes down the drain.

I went to Jeff's house yesterday and took a shower. There was shower pudding in the drain.
