Preferably long, slick, jet black hair attached to the scalps of true Metalheads. Enabling them to swing it around in a windmill like motion, asserting their dominance as a Totem of Metal.

A show that was once cool but is now a mere shadow of its former self. Too few metal videos, man...
If they show that godawful Zakk Wylde video again, I'm going to scream.

You know how some air-heads are pretty nice to talk to, and seem to have somewhat of a brain?
Well these type are not the case, they are hardcorly idiotic, ignorant, and superficial. They expel more stupid-ness in a second than our whole galaxy does in a year.
You: Oh hey, you are my team-mates right?

air-headbangers: PPFF, yeah...I mean... if you like guys who are into Jonas brothers and like, long-dongs

You: Go mosh to your face, you idiotic air-headbanger.

an equation that determines wether it is approprite to headbang to a perticular song. that factors that contribute to this equation are:beats per second of the drums, speed of guitar, number of guitars, speed of lyrics, screaming quality and vol of amps and no of amps
the equation is

MTh=Db+(Gs*Gno)+Ls+Sq/(AVERAGEAmpvol*Ano)

if the sound (Db) is greater than this treashhold, then u may headbang as the headbang threashold has been surpassed

A metal show on MTV2. The shis pretty formuliac: Shadows Fall video, Unearth video, 9 minutes of commercials, 8 more minutes of atreyu/avenged sevenfold. 9 more minutes of commercials, shitty videos interrupted by Jamey jatsa (who deserves to die, considering Hatebreed is so shitty), an eighteen visions video, then more commercials, then another unearth video, etc. Sometimes they actually show good videos, but its usually those shitty watered down metalcore bands. I usually get tired before a good video comes on and i change it.
