festy decayed old womans cunt. It is lacking of natural secretions thus gains a dry rubbery almost latex stretchy decrepidness. First observed when pacarskis mom spread her legs for me. However this is mainly used to describe a pimply faced arse vandal called pacarski.
Hey pacarski you rubbercunt
to wash ones ass. particularly after a heavy sweat. to buff the crack of ones ass for hygienic purposes.
"after a good ol fashioned crackbuff u could eat off that ass"
"looks like pacarski will need the crackbuff today if he thinks hes gonna score with those fags"
