The putrid blend of unwiped ass and sweat forming a sticky, smelly paste characterized by a horrendous odor, an unfresh feeling, and skid marks which are impossible to remove, rendering underwear permanently soiled.
That grunge muffin asking me for spare change has visible ass paste. I could smell it a block away!
think semi solid shit that squirts out slowly in a long tube shape as if it where coming out of a toothpaste tube. often required viggourous wiping afterward.
"toothpaste? nah, i use ass paste!"
