A facial accessory that instantly makes its bearer infinitely more metal and manly. This is especially true if one has had a beard since very early, ie. since they were thirteen. Beards tend to house hidden limbs and perhaps have a life of their own. The most famous example of this caliber of facial hair is Chuck Norris.
Don't fuck with Rob, he's had the beard since he was thirteen. It doesn't matter what music he plays, it's more metal than you. Always.
His beard goes clubbing every night after he goes to sleep and comes back in the morning to wake him up.
