Rooks, Kights, and Bish each have their share of the following (in no particular order): alt-potatos, dweebs, hoarde-monkeys, HO-tards, good sticks, newbies, luftwhiners, runstangs, roach drivers, flakpotatos, napoleans, exhibitionistic autofelatio practitioners, witty people, half-wits, niki dweebs, spitpotatos, crack monkeys, buff dweebs, score potatos, strat-geeks, nice guys, jerks, helpful people, alt-f4 lemmings, al gore rehash jokers, festabria bobbers, bearded clams, numbers geeks, suicide porkers, whiners, nazis, liberals, conservatives, jap-laggers, warpers, kill stealers, vulchers, twits, furballers, freeballers, sissy mary runners, wash-rinse-repeat "ACM" guys, cherry pickers, BnZ girls, stick-stirrers, el gay seven drivers, humble guys, pile-its, drunks, quiet guys, pubescent quakers, amish technophiles, dorks, jug tards, hellcrap dweebs, run-oh-nines, run-nineties, backwards firing typhoons, f-pork-u's, pee-fifty-runs, hunstangs, goon drivers, goon augerers, gv guys, l337 d00d's, campers, chute shooters, chute shooter whiners, Hartmann wannabees, Gabreski/Johnson wannabees, Rick James wannabees, Drex wannabees, Bong wannabees, bong smokers, "cheaters," cheaters, cable modem cable pullers, engine togglers, carbombers, milk-runners, insane-guys-who-jump-into-the-middle-of-fights-in-a-Ju 87 or 88-and-actually-shoot-everyone-down, beefdarts, lawndarts, Texans, inbreds, you're-a-peein's, Californicators, Kalifornians, Mavericks, Icemans, Sliders, overly sensitive '80s men, etc.
Sooner or later, you will fall into one of the above groups. The secret is to not really care if you are in one or even which group you are in.
