The whole thing about the bully is true, and the whole lying to others about you thing, but, its also about how his father didn't care about him and treated him like a mistake, even thought he was. His father always abused him and doubted him, just like the bully, and now hes showing them all(the people who doubted him) that he's made up for the mistake hes been believed to be. But don't forget that the whole band wrote this song, even though Corey Taylor's the only one to have singed in it. Which means that all of the members of Slipknot have some sort of relation or connection with them. This song represents a lot of what I had to put up with my dad. Hes told me I was a mistake before he left.
