The absolute most fucking intense thrash/speed/death metal band ever to come to life. They have appeared many times on MTVs Viva La Bam and Headbangers Ball, along with Guitar Hero 3 with their (in)famous hit "Raining Blood" and GH Metallica with "War Ensamble".

I cant give what I say next any real credibilty, but it would be FUCKING AWESOME. I have been told that their name is an acronym that is as follows

Satan
Laughs
As

You
Eternally
Rot

Spelling out Slayer.
" Trapped in purgatory, a lifeless object alive, awaiting reprisal, death will be their aquantance. The skys turning red, return to power draws near, fall into me the skys crimson tears, abolish the rules made of stone. Pierced from below, souls of my treacherous past, betrayed by many, now ornaments dripping above... Awaiting the hour of reprisal, your time slips away.
Raining Blood
from a lacerated sky
bleeding its horror
creating my structure
NOW I SHALL REIGN IN BLOOD!!!"

Slayer- Raining Blood

Get the Slayer mug.
An American thrash metal band that originated in Oakland, California. An influence to black metal. Also a member of the big 4 of thrash metal. Typical Slayer lyrics deal with death, war, suicide, the holocaust, and other dark subjects. While most newbies to the genre say that Reign In Blood is the best metal album ever, I and many others believe that Hell Awaits is better in every way. It is far more brutal and evil than Reign In Blood in both the lyrics and the guitar riffs. Don't get me wrong, Reign In Blood is a damn great album. It just gets way more credit than it deserves. I personally don't understand why they didn't make it bigger than Metallica. While Metallica took the sellout route to get more popularity, Slayer never sold out or got worse.
My ranking of the big 4:
1. Slayer
2. Anthrax
3. Megadeth
4.Metallica

My ranking of Slayer albums:

1. Hell Awaits
2. Show No Mercy
3. God Hates Us All
4. South of Heaven
5. Seasons In The Abyss
6. Reign In Blood
7. Divine Intervention
8. Diabolus In Musica
9. Undisputed Attitude
10. Christ Illusion
11. World Painted Blood

No Slayer album is bad, it's just that some are better than others.

Named after the American Thrash Metal band of the same name, the term Slayer may be used by a woman when telling others that she is menstruating. The term is a reference to Slayer's classic song "Raining Blood".
"I'm having my Slayer"

"It's that Slayer time of the month"

He asks her "Can I go down on you?"
She responds "It's not a good idea. I've got my Slayer"
"What do you mean?" he asks.
"I'm Raining Blood" she replies.

You might be expecting a great band. Slayer is playable character in Guilty Gear XX Accent Core Plus R, he smokes a pipe, writes haikus, founder of the assassins, has a hot mistress (kills her though), he can do Terry Bogard's buster wolf, and has a risk rating of S+.

Slayer and Baiken smoking with cigarettes, then for no reason fight and... You know what, everyone in the roster starts fighting each other for no reason.
