No, seriously by Kateus December 29, 2005

No, seriously

When someone doesn't believe how serious you are.

Hym "No, seriously. You have to at least acknowledge (internally at least) that the the situation is extreme. From Gangstalking, to almost jail, to retard sex cult, to publicly robbed by a millionaire², to gaslit by a psychologist. It never ends. It never ends! I'm going to got hunting and the deer is going to hunt me! The next time I go to eat my food is going to eat me. And to have you all sit there and wonder why anyone would behave immorally. 'No. You should have to do all that AND behave morally' as you snicker to yourself before you revel in the irony of the situation and your contempt of me. Revel in my sweet, silent suffering in your hellraiser suffering cult because that's what feeds your reality monster. Suffering is sacrosanct, after all. And now I hang. My grip loosening on the edge of the bottom rung. The people above me, on the edge? Staring down blankly and pissing."

No Lie Dead Serious 

The ancient pact that unifies truth from brother to brother allowing the validity of a statement to be unquestioned.

PERSON 1 :"Dude, I just sharded all over myself!"

PERSON 2 : "No Lie Dead Serious?"

PERSON 1 : "Dude, No Lie Dead Serious!"
