gearhead 

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.

Stereotyped Hot Topic "Goth": Check out that gearhead. I bet he listens to Nine Inch Nails.
Overhearing Gear/Rivethead: Shut your tube filth pig! Nine Inch Nails is shit! I listen to Apoptygma Berzerk, KMFDM, VNV Nation, ohGr, The Gemini Ritual, :Wumpscut:, Skinny Pu... Why the fuck am I telling you this?! *proceeds to stomp poser goth to death*
