12.
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*

6.
A musician (most common in guitarists and drummers) who spends more time reading about and buying gear than they actually spend playing music. Gear heads think that by spitting out a flood of brand names and model numbers to their friends that they will sound more intelligent than they actually are. Also, they hope their new equipment will compensate for their lack of practice. Truthfully it shows they spend too much time on the toilet reading "Musicians Friend".
guy: I would let him in this band but gear heads are annoying
