shallow shower

a cold speedy shower taken after strenuous physical activities that result in copious amounts of sweat, such as sex or sports. Takes off only the outer layer of sweat, hence "shallow"

Ernie: fucking hell dave, i'm as sweaty as a duck in a toaster after our recent anal frolicking.
Dave: balls, and your mother's coming in five minutes... time for a shallow shower, i think!
