Indeed, cursing is considered a fine art among Klingons. One of their aphorisms, translated idiomatically as "Curse well!", literally translates as "Shoot curses forcefully!" They consider curses as weapons which must be propelled to their target, much like throwing knives. At least one Klingon epithet, petaQ, seems to be used to refer to "someone who has no honor." It was used of Worf by other Klingons during the period of his discommendation.
