Shit Idiot Brain Fungus (S.I.B.F.)

The Shit Idiot Brain Fungus (or the S.I.B.F. as it is considered in the medical community), is one of the most deadly diseases known to mankind. It strikes at the cerebrum section of the brain and completely shuts it down. This leaves the victim in a state of eternal idiocy and stupidity. This condition affects countless people worldwide, and the symptoms are completely unnoticeable until it is far too late.

This disease was first invented as a bioweapon by Dr. J while he was locked in the basement of 2000 Presidential candidate Alfred Gorestrum (Al Gore). He planned to use this bioweapon on Senator Ted Cruz of Texas in an attempt to make him a raving dumbass. Little did Dr. J know, however, was that Ted Cruz was already the dumbest of raving dumbasses. Unfortunately, the fungus did spread to Ted Cruz and he is now a walking and talking gravemind of the fungus and looks to spread it to all those he comes into contact with and speaks to.

I am writing this definition from my bunker in Southern Kosovo in the hope that some wandering internet-goer finds this and puts an end to the fungus, and Ted Cruz, for once and for all. This is my last message to the world, goodbye.

Person 1: "Yo, you want to hop on the Roblox Pacer Test Game, I really think that it might be a very enjoyable experience."

Person 2: "Bro what the fuck are you saying, have you or a loved one been in contact with a carrier of the Shit Idiot Brain Fungus (S.I.B.F.) or Ted Cruz himself in the past 30 days? You seem like you've come down with a real bad case of it."

Person 1: "Oh no, what if you're rig--- djasdfuiho asdhfgiubsf." *collapses to the floor in a broken heap and as a husk of his former self*
