Metalgasm 

Caused while listening to a particularly hardcore riff in a metal song. May cause cranial combustion, which is then known as a Ubermetalgasm.

Whoa...that riff in Judas Priest's Metal Meltdown gave me on hell of a metalgasm

metalgasm 

An orgasm derived from listening to music of the metal genre. Usually occurs during screaming/growling parts of a song and will result in goosebumps and a smile.

Girl: Have you ever listened to Otep?
Boy: No, why are they awesome?
Girl: Awesome...yeah...so awesome I got a metalgasm the first time I listened to them.
Boy: ...
Girl: It was almost better than a real orgasm.
Boy: Wait...What?

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.

Metaplay 

In a RPG, metaplaying is the insertion of out-of-character knowledge into an in-character area. This is typically against a fully fledged RPGs rules and will eventually result in a ban.

Sarah reads that Tom's character (Bob) is involved in a top secret project for the government and doesn't say anything to anyone about it. Sarah engages her character (Kelly) with Bob. Kelly knows all about Bob's top secret project and his job details, despite Bob not having said anything to Kelly (in-character). Kelly metaplayed Bob.
