(n.) The act of cumming in one's own sheets, rolling around in the goo, sleeping, and awaking with a toga held together by one's own 100% au naturale adhesive. Revered as one of the most respectable self-gratifying acts from 27 BC to 476 AD. Can also be used as a verb, in which case one would supply the necessary adhesive to another's bed, presumably while the other was already asleep, and thereby adorning the "prankee" with a friendly toga.
So I knew about a toga party a few days in advance that was going down in Greektown, and I thought to myself, "My, wouldn't it to be interesting to be the only person at the party with an all-natural toga?" So I totally pulled a Roman Emperor the night before and was a huge hit at the party. Plus, all the chicks were totally attracted to the smell.
