When you jerk off in the shower, and the semen mixes with the water, creating a sticky, white glue otherwise known as shower cement.
Damnit Billy! You could have cleaned up in the shower! My feet are stuck to the tub with all that shower cement you've been making!

The Towel you use when you didn't do laundry therefore running out of your full size shower towel. The Shower napkin is the midsized towel usually used as a hand towel or wash cloth. The shower napkin is used for wiping the water off while you freeze from being cold and wet because it wont even fit all the way around a newborn baby

When a woman(preferably white) is on her knees surrounded by many black men circle jerking, with a burning passion, over her body. She then cleanses herself in the sea of semen.

A white glob of semen found floating in a public or possibly private shower. It resembles an oyster.

Using a detachable massaging shower attachment to wash just your anus after you take a crap rather than taking an entire shower. Basically, the same action a bidet would offer but for those who don't own a bidet.
