For those who don't speak Bulgarian (like me), google translate of "не сме народ, а мърша" is "we are not a people, but a carcass". Though I'm sure a native speaker would probably have a better translation.
It's good enough for government work! I didn't translate it because it can come off as far too inflammatory - it happens to be a line from a well-known poem by one of the founders of modern Bulgarian written literature.
