Alvin Movie Poster

Hear's awsome minisized Alvin on his own movie poster for the Alvin and the Chipmunks movie. I am unsure what "supercool" at the top of the poster means. I think it's German...does anybody know? Anyways, I have another poster like this with Simon on it and at the top it says, Superschlau I'm guessing that supercool means super awsome
