I thought this was easily the best single off this album. I don't particularly care for the Lady Gaga Diss as it's waaay easy to take a cheap shot at someone famous to get some attention. Still, the video was gorgeous and insane and the little details and layered african drumming was fucking amazing. 5 Stars.
They are most definitely doing "a thing" by pretending to be white-trash South African ignorant scum. The music they made with Max Normal had a different approach and Ninja (back then using a different alias) used to portray different personas in different songs (most of the time he was a frustrated business-type rap salesman), and one of them was Wad-e (which was essentially the character he is playing now as Ninja). Some time ago I posted a video of Max Normal here on 73Q, if you follow the tags you should find it.
So yes, it is all an act, it's a funny and outrageous and good one though.
