The man's name is M-U-S-S-E-R, not M-U-S-A-R or M-U-S-S-A-R. I just checked Google German to English. "Musser" is a German word, but the other two are not.

I actually studied German in college at a major university. Did you graduate community college or even high school? Perhaps you rode the short bus to school.

People are continually taking words that have some similarities in spelling and making crazy-ass assumptions about them that have no basis in reality.

It doesn't matter a fig what "Musar" means, when that isn't the guy's name.
