look up any word, like thot:
A woman's vagina with enormous external hanging purple-ish colored "mud flaps" that is so gross and nausea-inducing that it reminds one of a smashed possum on the roadway i.e. roadkill pussy.
"Did you see Noreen's ugly pussy at the pool party last Saturday when the bitch whipped off her granny pants-like swimsuit bottoms?? I almost lost my lunch!!"

"Yeah man, her stuff looked like roadkill pussy!! I wouldn't fuck that bitch with YOUR dick!!"
