Fans use tools to rearrange the characters' voice lines (voiced by Faizon Love for Sweet and Young Maylay for CJ) to make them say outrageous or repetitive things.
The quote is a modified or emphasized version of dialogue from the game's protagonist, Carl "CJ" Johnson , and his brother, Sean "Sweet" Johnson . In the original game, Sweet is the stern leader of the Grove Street Families who often reprimands CJ for his actions or for the state of the neighborhood.
