If you look at the in-game dialogues there is some pretty random stuff.

"Brass Blade: I told those damn Ala Mhigans to cover their piss!"

What does this mean? Even if I consider a possible Japanese to English translation the original meaning is irrecoverable. Quite a lot of dialogue is meaningless drivel. "Cover their shit!" would work because the actual meaning is not how this phrase is understood, however "Cover their piss!" still retains its literal meaning.
