Not being clean shaven. (specific to females)
When your pubic hairs are short enough to feel like needles but not long enough to lay over.
Similar to a mans 5-O'clock shadow.
Sally: hey feel my muff!
Doris: What why?
Sally: just do it!
Doris: Feels it... "OUCH" damn shave that PORCU-POON!
Sally: That should thwart off any man!
Whats a Porcu-poon? ITs a mash up/spin of the words PORCUPINE and POON.
Man and woman lay down in bed together..
Woman tries to spoon with man.
Man Screetches! "Woman" he says... "Go shave that Porcu-Poon!"
while he recovers from the multitude of needle like stabs on his backside.
