Mentally Hilarious 

A 'better' alternative to using the word 'crazy' or 'insane' to someone. Or just a fun way to call someone crazy. Also, 'mentally jolly' can be used. From the Family Guy episode 'The Fat Guy Strangler'.

"Dr, is my brother really insane?"
"Mrs Griffin, we don't use the word 'insane', we prefer the term 'mentally hilarious'"

One of the earliest forms of alternative metal.

Examples: Rage Against the Machine, Faith No More, Living Colour, Primus, some Red Hot Chili Peppers, etc.

-This is good music. The bassline is complex and groovy but the guitarist is tapping and shredding like a madman.
-Yeah, that's funk metal.

Metal Ear 

An acquired ability to decipher the lyrics of Metal singers without any trouble at all. Some Metalheads never acquire this ability, having to either resort to searching up the lyrics or making up their own. If you ask what the lyrics to a song are near a person with Metal Ear, you'll likely be regarded with disgust and maybe an exasperated answer.

Guy: Why are you even listening to this crap? I can't make out a word of it.
Metalhead: That's because you never listen to it, and you obviously don't have the Metal Ear.
Guy: You're lying, I bet you don't even know what they're saying.
Metalhead: Get out of my car. Now.
