fighting with the invisible ninjas all around you. This is done to bands such as terror, e-town concrete, unearth, and bands that yell a lot.
jeez, i went to the e-town concrete show last night, and i got kicked in the stomach by a skinny kid wearing girl pants, and a red bandanna like a cowboy, and a army hat, and a shirt way too small for him. I then went into the pit, hardcore danced for a bit, then simply punched him in the face and walked out.
point proven? hardcore dancing is fun until you get hurt.
