The end all to any argument. Used when one either has no intelligent argument left, wants to try and use "no u" as an intelligent argument, or want to piss someone off. Most effective after one has been insulted.

The extremely boring science of explaining why chemical stuff happens. Studying chemistry instantly removes much of the fun that can be had when lighting things on fire by explaining how it happens. Teachers of this heinous subject are believed to have no soul, be mentaly unstable, or both. Also, people on the chemistry team enjoy similar status as those on the Math team (complete losers who find fun in academic achievement).
Jack: Yo Jill you wanna come to the chemistry competition with me? We're gonna totally own those guys from Sackville High. Their pocket protectors are pink. Those losers *nyehehehehehe*
