the greatest thrash metal band ever

How does one describe Slayer? There is no definition for Slayer. Probably because Slayer doesn't belong in something as politically correct as a dictionary.

originated from danish metalheads- used as an indirect way to show dissapproval of either a show(concert) or just music being played. if the music is horrible or the concert is- you yell out "SPIL NOGET MED SLAYER"(play/put on some slayer

Slayer is someone who always slays like Lauren

An exclamation made by visitors of a rock or metal concert. Originally, this was to ask the band (usually a cover band) to play a song by the band "Slayer" (a trash metal band, and one of the most brutal bands in the history of Metal music that gained world fame). However, the use of this exclamation has now broadened; it can also be used to ask the band on stage to play something louder or harder than what they're currently playing.
The exclamation can also be used in a bar, adressing the DJ if he plays crap music.

A great thrash metal band, and contrary to popular belief, is NOT only loved by angry white kids/Satanists. They are not a Satanic band, and they are actually quite the performers, but most people can only hear loud raging noise the first time they hear it and thus judge Slayer to be a crappy band.
