Player 1: I FUCKING LOST TO A BRAIN DEAD ASURI
Player 2: What makes them brain dead?
Player 1: They spam their sigs like there's no tomorrow. But the thing is they have less than a half of a brain cell, unlike normal sig spammers.

The literal death of the brain, brought about by severence of the spinal cord or any major brain damage.

brain dead 

the link from reality and fantasy are broken. there is no pilot in the cockpit if you know what I mean. the results of too many drugs can do this to you. you can be born this way. whatever the reason, you state things out of your ass without a reference, and you don't know nor care how accurate your statement is.

After I took over 10 years of bong hits, I have been left virtually brain dead, leaving only the cartoon network as a compatable reference.
