The singer had a troubled upbringing as his mother kicked him out of the house at only 16 after he became a drug dealer. However he began to clear up his act as his career of a rapper began to take off.
He said that he chose his stage name because a pitbull is 'everything I am'. With reference to them being outlawed in Dale country, they are too stupid to lose, and they 'bite' to lock.
