Well, think about it, mack means killer or gangster?? "Life of a Mack" - GTA V (radio los santos), in that song the person narrating refers to a young man living in the life of a mack, he refers to fucking bitches and doing other "gangster" things. rape is to rapist as mack is to mackist
mackist - someone that has done gangster shit and idk why i'm writing this.
