Slayer Mouth-off

When two hardcore metalhead slayer fans argue, possibly for hours, about how much they know about slayer ect. it is a diverse bonding ritual of slayer fans, when they feel threatened by another slayer fan. slayer fans don't usually like other slayer fans.

typical slayer mouth-off..

slayer fan #1: how many slayer tee shirts do you have?
slayer fan #2: 5. how many do you have?
slayer fan #1: 5. how many slayer albums do you have?
slayer fan #2: all of them. how many do you have?
slayer fan #1: all of them including the one that they never actually released. i had to drug Tom Araya to get it..

Jerking your mouth off

When all someone does is talk shit and the more they do the more toxic waste comes out.

Guy: I can't stand John Walsh. All he does is talk about fugitives being on the loose! He needs to get a life!

Girl: Quit jerking your mouth off. I can smell the shit when you open it.
