Soulja boy is now the title of the song you are thinking of. Soulja Boy is the artist who sings it. The song is either Crank Dat or Soulja Boy Tell'em.
He used to be Soulja Boy but changed his name to Soulja Boy Tell Em due to a rapper already having the name Soulja Boy. Check out Materialistic B*tch by Trill Fam...first verse is the original Soulja Boy.
Nothing because there is only one soulja boy and he is the best and no one can become soulja boy no one can change who he is so whoever put this question you cant do anything because soulja boy is soulja boy and you cant do anything do be him.
