Off the bat: Juicy J, Wiz Khalifa, and Ty Dolla $ign have all heard "Addams Groove" and "Ninja Rap." As accomplished businessmen who don't give a fuck what anyone thinks, they know how profitable movie-themed raps are and how quickly they go from platinum singles to pure camp in the public eye. So it's unfair to assume that recording a dubstep rap song called "Shell Shocked" for the new Teenage Mutant Ninja Turtles movie was done so out of ignorance. They know exactly what they're doing.
Aside from lining the artists' pockets with free Dominoes for life and winking at the past, the song exists to begin a revolution. Read between the lines, and it'll show you how anyone can battle the inequalities of the world. The proof is in the (pizza®) pie:
"That's my fam, I hold them down forever/Us against the world, we can battle whoever/Together ain't no way we can fail/You know I got your back, just like a turtle shell"
Juicy J starts with a specific reference to the accusations of corruption that plagued this year's World Cup.
"Knock knock / You about to get shell shocked"
This line is sure to be hugely controversial due to its strong and unequivocal stance on the wars and instability in the Middle East.
"By my side Imma keep my brothers / Live or die man we need each other"
Family and loyalty are essential to survival, especially if you're an endangered Clanwilliam Cedar tree, referenced by Wiz in this line.
"I told your girl but you might not believe me / She taking pics for me / Told her smile for me /Pass her off I'm a real team player"
Teenage Mutant Ninja Turtles will have sex with your girlfriend, sometimes one after the other.
