Infected Mushroom? They're not satirical in a sense like Die Antwoord, but they do have some pretty interesting sounding beats, awkward voices and guitars riffs - stuff that the boring individual probably wouldn't listen to. Their sound spans very widely, and I thought you might like since you appear to be into rock.
But back to the actual question, there's nothing really out there like Die Antwoord. The closest thing I can think of off the top of my head is Bom Bom by Sam and the Womp, and that's nothing like Die Antwoord. Same level of odd though. [link]
I haven't actually tried to get Jack Parow yet, I mean I enjoy what he's done with Die Antwoord but haven't gotten there yet. I see a lot of mixed reviews of him from Antwoord fans. I really just want MaxNormal.TV right now but I can't buy it anywhere that I know of and my download is stuck at 54% :c
It's okay to like diametrically different things. I don't understand people who are exclusive about other things. In that matter, I absolutely worship Slayer and yet I really really like Die Antword and their philosophy. I think they're really intelligent people who found a way to make money and have a good time. Also they show some big balls in their interviews and concepts. Respect.
