look up any word, like dirty sanchez:
 
1.
nasty masterbating, usually the kind you accidently witness. Potentially involving unconventional lubes such as sweat from mowing the lawn, old milk, taco drippings, or water from under your fridge.
Walked in on my friend nasterbating the other day, his blow up doll was wrecked. It hurt my soul to witness that.
