“My styles are slick/ Your body, bitch, that I will chop in pieces/ No fuckin’ clue to the 5-0 click, no fuckin’ witnesses/ They only saw the mask of Jason that I had on my face/ The scandalous bitch is so-so slick, that’s why I got away safe.” That’s how Gangsta Boo, the Devil’s Daughter, introduces herself on “Mystic Stylez,” the title track from Three 6 Mafia’s debut album. When she wrote those lines, Gangsta Boo was 15 years old.
