A metalhead is kind of self explanatory, it's a person who listens to a lot of metal. Metal heads can be classified for long hair, black clothing and band tees BUT, not all metal heads look like this. Metalheads tend to dress however they want. A lot people call them selves metal heads, because the only bands they listen to is Slipknot and Disturbed. This is personally an insult to true metal heads, because true metal isn't recognized, such as Ozzy Osbourne, or Amon Amarth.

Ass Kickers And soldiers of music. kinda like hippies with black clothing and attitude. Moshers and definitely not goths. and metalheads get laid a lot.

Basically Someone who respects the Genre, and even though they might not Look like a typical sterotype, or listen to metal all the time, Has a deep love of the Blastbeat.
Metal Is About whats inside, Not whats on your sleeve.

1. Someone who listens to metal music and/or any of its sub-genres (Heavy Metal, Classic Metal, Thrash Metal, Glam Metal, Death Metal, Black Metal, Industrial Metal, Power Metal, Progressive Metal, Hair Metal, Doom Metal, Alternative Metal, Symphonic Metal, Gothic Metal, Metalcore, Nu-Metal, ect.)
Someone who is open minded and respects other people's tastes in music, because they realize that their music isn't everyone's cup of tea.

2. An arrogant, elitist hypocrite who believes that his or her tastes in music is better than yours.
Someone who will criticize bands they don't like for doing things you'll see their chosen bands doing all the time (which they will conveniently ignore.)
Someone who complains about pop music and how bands such as Linkin Park are corrupting the metal industry.
Someone who mentions how much they hate Lady Gaga on a youtube video that has nothing to do with her to begin with.
Someone who constantly argues with the "no true scottsman" logical fallacy by saying that metal bands they don't like simply aren't metal (even though they are somehow corrupting the metal industry, see Linkin Park again.)
Someone who wants to tell you what to wear, how to act and what religion you should follow, while simultaneously accusing "mainstream" audiences of doing the exact same thing.
A homophobe that will call you a fag if you like music that he or she doesn't.

Someone who take's there metal seriously, and would give their life to save Dimebag Darrel R.I.P.

Metalhead is a person who listens to metal music, no matter what subgenre of it.
A metalhead belongs to a subcluture which consists of metal music, dressing up metal like studs, spikes, leather or black clothes & band shirts in general. They often attend countless metal shows with all their metal buddies. Nothing wrong with it.
But metalheads divide in two, one side has the intelligent and the other the stupid. The first side usually had good grades at school, they never abused alcohol and are generally very educated, smart and intelligent people who just happen to like heavier music.
The other side however has people who nearly dropped out of school, drink alcohol more than anything else, swear, are violent and lack of brains.
Often these two sides of one subculture clash with eachother, making metal subcluture one of the most notorious and controversial of them all.
Metalheads also tend to be elitist towards the music they don't listen, EVEN inside their own subculture. check example 1
Not all metal listeners are metalheads. They do enjoy heavier music to a great extent, but they choose not to dress according the subculture and are very open to all music. They do attend metal shows, but every gig that comes to the country isn't a metal must. Those people aren't metalheads, they're metal listeners. check example 2

People that head bang to metal music. (Which does not include Insane Clown Posse) They hate Emos because they basiclly mock our stye whether your goth or just a band t-shirt wearer. Dont take much to get pissed off and can kick peoples ass physically and verbally. Dont need a group to fight someone. Enjoy walking around at night with friends and listening to metal all the time and sharing underground metal bands with friends. Wear band shirts not prepy clothing including American Eagle, Abercrombie and Fitch or Hollister and most Metalheads hate people that wear that shit some wear that though but there not true metalheads because preps are pussys and metalheads are not. Sometimes had long hair intended for head banging. Hate the government in a none hippie way. (influenced by Arch Enemy or rage against the machine) But the most important thing is to be a complete badass.

considerening now,because of all these different but very good subgenres of metal, i don't even know anymore!!!it is used to describe the dedicated and true metal fan.sadly we now judge some person just because they like slipknot.look im a fan of all metal genres and i just need to say it:we have turned against each other. in the very begining it was about the music & fandom & that was all.Now we are all in disarray,pitted against one and other.heavy,nu,traditional, or whatever other subgenres that came into the picture,deep down all thesegenres end with one word: METAL!

My opinion of what a metalhead really is: a person who is a dedicated fan of metal music. And I mean ALL types of metal. Whether it be nu-metal, metalcore, deathcore, black metal, heavy metal, symphonic metal, death metal, thrash metal, Swedish metal, hell, even folk metal from different countries like South Africa.

You don't have to have long hair, wear black all the time, and whatever. Metal should be a way of thinking and a way of life, not who is more of a "true" metalhead because they don't listen to Slipknot because they are nu-metal and that equals fail. You should be glad they are listening to Slipknot which is some form of metal, instead of Fall Out Boy or something.

True Metalheads learn to appreciate ALL FORMS/SUB-GENRES OF METAL. Being glad that at lease they are listening to metal, and also teach the newbies who honestly want to learn new metal bands and learn to love Metal and at lease appreciate ALL of its Sub-genres.

Also metalheads should accept other metalheads from different backgrounds, whether race, color, creed, religion, culture or whatever country your from. We are one big brotherhood and we all love metal, and that should be good enough!

BE GLAD THE NEWBIES LIKE METAL.
Cause alot of us may have well started with those bands way back then.
