When a member of the SomethingAwful.com forums, known as a goon, kills oneself. This is almost certainly followed by a permanent banning of their forum account by the administrators since they are dead.
"I heard (SomethingAwful forum user) killed himself because he was long-term unemployed, his girlfriend left him, and he was facing homelessness."
"Another goonicide? He made some funny posts. I'll miss him." =(
Made popular by the black fella in the goonmobile (dodge challenger) being filmed while driving without pants with his meat out in the drive-through. Later he killed himself. Forever being known as the goonicide.
"Yooo did you see that the freaky guy took his own life? #goonicide"
