Black Metaller 

Anyone who is into black metal. Black metallers often are known to appreciate Black Metal, norway, philosophy, classical music and sometimes Satan (usually it's just the band members who do the whole Satan thing.)

Although Black Metallers are considered nasty people to be around, they aren't often around due to the lack of live performances from bands. Very few bands perform live and when they do I can admit the fans go crazy but look at the anarcho-punk scene or the american rap scene? The only difference is the fact Black Metallers keep it far more underground.

Everyday joe: I don't like the idea behind this "death metal" music of yours

Black Metaller: It's called black metal and how can it be harmful if you never even heard of it?

Metaclysmic 

To exist on the level equal to all that is good in both mortal and immortal worlds.

I don't think we will ever hear a band in our time that is great on a metaclysmic scale

Minus the Bear is metaclysmic.

mentally sober 

A term used by a woman to defend her asshole boyfriend after he gets drunk while he is supposed to be spending time with her.

Yeah, Noah was drunk on Halloween. It’s okay though because he was mentally sober.

METALLICAHOLIC 

The act of being addicted to the best band of any kind ever created, the one and only Metallica.

Metallica Members are/were James Hetfield(Vocals Rhythm Guitarist), Lars Ulrich(Drummer), Dave Mustaine(Original Lead Guitarist), Kirk Hammett(New Lead Guitarist), Cliff Burton(original Bassist), Jason Newstead(Replaced Burton When Burton Died), And Robert Trujillo(Current Bassist).

This music kicks more ass than Rush and Van Halen combined. I guess I am now a METALLICAHOLIC!
