a grouping of several codified dances often seen performed at hardcore shows.
the moves will vary with specific subgenre of hardcore, the politics of the scene involved, and individual choces of those dancing.
two-step: a fairly nonviolent, unthreatening move similar to punk skanking. emphasis is on style and variations of arm movements.
windmill: many variations, but generally includes flailing arms in wide circles, often spinning the entire body in the process. often leads to spin kick or jumping spin kick.
spin kick: a spinning back-kick. if you were to hit anyone it would be with the heel of your foot.
jumping spin kick: jump, spin in midair, and kick forward with your back foot.
floorpunch/ picking up change: bend over, pretend to grab or punch the ground, alternating hands. bring your hand back to your back pocket area (as if putting change in pocket) if you want to not hurt anyone, or flail the arm away from your body violently. while grabbing/ punching with the right hand, stomp with the left foot. and vice versa. can be performed while stationary or while moving sideways or forwards. this can be a violent dance if the kid decides to use his/ her arms (esp. elbows) as weapons.
kids may also be seen running back and forth in front of the band, sometimes jumping a whole damn lot, raising their fists (often with an outstretched index finger) and singing along. kids also pile onto one another and scramble to grab the microphone and sing a line or two if the mic is proferred by the singer of the band.
some of these dances are not considered acceptable at certain shows. kids generally do not spin kick at posi, youthcrew-type shows. it's just not very posi. and there will often be no two-stepping at more metal-influenced shows. some hardcore scenes are more influenced by diy punk ethics, some more by kids wanting to just beat the shit out of each other and wear fancy clothes. this will affect the dancing present at a show in fairly obvious ways.
the other definitions of hardcore dancing present here seem to be more from younger kids who listen to new-school metal-influenced hardcore. they would claim no tie to the punk community or the ethics associated with it. this is obvious from their blatant homophobia and general meathead attitude. they will sell out hardcore pretty qhickly, and if any are straightedge, they won't be for long.
