A deadly type of flatulence, occurring when an individual has an overuse of steroids or protein.
It is actually documented on Canadian Biological Containment Registry (CBCR) that these farts are a biological and nucleur threat and those that inhale this deadly substance will become a zombie or piece of brocoli.
