I never knew there was a specific name for this. I recall years ago(many years, on an old Usenet forum), asking what a, "superman" was. Turns out its when your lover cums on your back, and you fall asleep directly after. The next morning when you get up, the bed sheet will be stuck onto your back like a cape,,. The internet makes all our lives so much richer these dayz, dont you agree? ;)
