When someone is fucking you in the ass and you are shitting simultaneously, which causes the shit to encase the penis and come out the sides of the asshole. The shit fans out around the shaft making pasta like shapes.
We ran out of lube so we had to make asspasta to ease the anal stretching.
The pastey shit you take after eating mexican or indian food. Sometime collets on back of toilets and takes many many flushes to be washed away..sometimes also taking many many showers to be washed away from your in betweens.
1. Man this hobo smells like asspaste.
2. While traveling in europe i had many cases of asspaste.
