PICARD: Mister Worf, what does "p'tak" mean
WORF: properly pronounced "petaQ" - it is difficult to translate - it refers to one who manually manipulates their own genitals for self gratification - the closest word in your language would be a "wanker"
PICARD: I see - and how does one respond to this insult ?
WORF: The correct response is to pose the question "Who are YOU calling a wanker?" .
