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.

I'm studying Japanese at University and while I think it's kind of a nice challenge I wouldn't say it's the most badass language. Most of the kids these days only want to study it because of Anime, Manga and Visual Novel I guess. I actually like my mother tongue German better, it sounds so crisp, and precise, like a well crafted clock.
