What exactly is a rejmorgh? I know it translates to worrywart, which translates to worryguts, but even that doesn't mean much to me.
Someone who worries.
Just that and no more? (I just thought the "not brave" thing meant there was an extra nuance to the Klingon word.)
This sentence is not defining the word rejmorgh; it's just a sentence someone came up with.
Ah, just someone's opinion then. Maybe the same character who said tribbles make them happy ;-)
