True Metalhead 

A metalhead who isn't any of the following:
*A massive gatekeeper (e.g: "Oh, you like .....? Name 5 songs.)

*A huge elitist (e.g: "Core is so cringe, I only listen to blackened death grind doom sludge.")
*Highly opinionated (e.g: Don't listen to ....., they're crap.)
*GG Allin

He was a perfect example of what a true metalhead meant.

A True Metal Head 

'Just a general Metal head typically seen with non-tight jeans, casual shoes, and an Iron Maiden shirt. Will listen to a wide spectrum of metal from Iron Maiden, Led Zeppelin, Black Sabbath to Pantera. The best and least annoying type of Metal head, tough, down to earth, he doesn't feel the need to tell the world he likes metal with gimmicky clothing styles or cliques, he simply gets on with his own life and lets other get on with theirs.'

ex.1:
kid1: 'dude, that kid is such a true metal head'
kid2: 'yeah, with is non-tight jeans and his casual shoes'
kid1: 'must be one of the last of his kind'
