hoop residue
fecal matter mixed with other bodily fluids which 'mature' in the crevices of the butt..density, colour, smell and texture may vary from hoop to hoop..ie a trucker may have more pungent and courser residue than a ballerina..tends to accumulate and harden around stray hairs..tramps have this in abundance..can also be found under the nail if ass hole is vigorously scratched
my mate was buggin me so i scratched out some dam fine hoop residue and smeared it on the mothers' mints..oh how i laughed when the silly little ring piece ate it...i hope it went down smoothly!
