1.) A large amalgamation of pubic hair collected over time, that closely resembles a small woodland mammal. Mostly in and around the toilet and bath tub area. (Most squirrels hide nuts, most nuts hide squirrels)
2.) Pube Squirrel aka pub-ba-kis maximus; a wookiee-like cluster of scroto-centralized pubic hair lurking behind the base or seat of the toilet.
"I swear I saw that pube squirrel move!"
"Dude, you have a pube squirrel hibernating behind the toilet seat."
