Most Badass Language

My vote is German.

Sounds very rough and intentional, aristocratic,  there must have been nothing more scary in the 1940s to people then listening to germans speak.

You are all wrong. The most badass language is Somali. Have you ever heard a group of male Somalians (?)have an ordinary conversation? It sounds like they are about to rip each others heads off! IMO that is a badass language! BTW, I'm not Somali, I've just heard them quite often on the bus.
