There is a question that includes both my favorite fandoms – “What’s “loser” in Klingon” (quote from E11S6 “Doctor Who”). I am really surprized that I can’t find answer to this on Web, so am asking for most correct translation from you. My knowledge of Klingon is very bad, but in local trekkie chat we were able to produce two possible variants:
vonlu’wI’ was suggested by a person with some knowledge
vonlu’eghghach was my idea – “somebody that failed himself utterly”
Sorry if it’s a frequent question.
