Good question. The Klingon language is definitely well-developed enough that many Star Trek fans can actually speak the language coherently. Mando'a, on the other hand, was developed largely by one individual and is rarely ever used by fans outside of hardcore Fandalorians. The solution: Hibirar Mando'a, gar hut'uunla di'kutla, shabla dar'manda aruetii! Learn Mand'a, you cowardly, foolish, [redacted] up, soulless outsider! I kid, I kid.
