See also rivethead for a more precise definition. In a nutshell, one who listens to industrial mEwzIk (a.k.a. music) and has a look very rarely seen. The most common triats of the gearhead/rivethead include WWII fighter pilor googles/welding goggles, army helmets, anything remotely militarian or camoflauge, large, black, steel-toed boots (used for stomping the enemy or rivetheads, the raver), most anything UV, sometimes utilizing computer parts as accessories, with most anything original and futuristic. The look is, in most common high school cliques, quite new and original.
