Decibelic 

Something that is very loud, any sound that is voluminous, i.e. has lots of volume. We measure sound using units known as decibels. A decibel is one-tenth of a bel, which represents a logarithm of a ratio. For instance, a jet engine is about 120 decibels. It is therefore decibelic.

Dude, this concert is so decibelic, I think I'm gonna have to go outside before I go deaf!

decibel

My subwoofer is at 2.12 decibels out of a possible 30.00 decibels, and still the neighbors are complaining.

Neanderthalis Decibelus 

A type of loser.
Specifically a loser with a compunction to force EVERYONE to listen to their crappy taste in music, often using a lame stereo system.

If that Neanderthalis Decibelus doesn't turn his volume down I swear I'm gonna shove that boombox up his rectum.

grebo 

West Midlands slang word for rockers, bikers, greasers etc. In the late 1980s it was used by the UK music press to refer to a specific scene centered around the bands Pop Will Eat Itself and Crazyhead. The term never found favour with readers of 'the inkies' (Sounds, Melody Maker and the still extant NME) and was soon dropped. Now often used in predominantly working-class areas of the midlands and the north to mean someone who listens to rock-derived music and/or dresses in a manner that suggests they affiliate themselves with rock music of some kind.

Some grebo passed with Sabbath playing on his stereo.
The Poppies are at no. 17? God, a grebo band in the charts!
They're playing nu-metal now, bloody grebos!
