For those who don't know who GG Allin is, I made a thread about him that was immediately taken down, so I'll recount his acts of gross controversial hilarity in one quick paragraph.
GG Allin was the skin head neo nazi punk band singer who had a cult following throughout most of his "professional" life. He was known for self mutilation, defecating on the stage, and attacking audience members during his shows, never missing a single word of his offensively politically incorrect lyrics. He always claimed that he would commit suicide on stage during a concert, but died of a heroin overdose in 1993.
And this chef just compared himself to him.
