G.R.O.S.S. is an anti-girl club, as popularized by Calvin & Hobbes. The name is an acronym that stands for Get Rid Of Slimy GirlS
Based in a treehouse (with occasional emergency meetings inside a cardboard box), the main objective of G.R.O.S.S. club is to annoy, bother, and harass girls. Calvin and Hobbes are its only members, and they sometimes plan missions to do so.
