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.

Look for local chapters of G.R.O.S.S. now forming in a neighbourhood near you.
o Calvin: "I've got it! We'll call our club G.R.O.S.S. - Get Rid Of Slimy Girls! That way, Susie Derkins can't join!"

o Hobbes: "Is she slimy?"

o Calvin: "All girls are slimy. Now the first order of business is to elect officiers."

o Hobbes: "I get to be president! I get to be president!"

o Calvin: "Oh, no you don't! This whole club was my idea, so I get to be president."

o Hobbes: "Ok, then I get to be king and tyrant."

o Calvin: "Hey, no! That's what I want to be! You can be president!"
