A large woman, often times unkept. At least six feet tall, poonquatches have large feet, are slightly hunched over, and most likely have hairy, hairy beaves. They are often seen wandering aimlessly around bars in a state of drunken stupor lurking for their next victim.
You are sitting on your couch- you glance at your yard and see a shadowy figure shuffling and hesitating beyond your hedge. By the time you race outside to confront the trespasser... all that is left is a steaming mound of ...POOP! You have been victimized by the elusive Poopsquatch!
The hairy pubic area around a womens genitals. Only a true pasquatchi if it's large, sometimes migrating down her thighs, emitting a strong odor and generally unkept.
Man, I took home this chick the other night and when she slipped out of her dress I saw she had the biggest, furriest, brightest fire engine red pasquatchi I had ever seen... I could smell it from across the room.
