Plurk

A verbal substitute as a censoring interjection; to replace profane speech with kinder language. Used as a substitute for coarse or profane exclamations, especially. those beginning or ending with a plosive or fricative consonant; an expression of surprise, irritation, or emphasis. --- Formed from the cultural acronym PLUR (Peace, Love, Unity, Respect) with the appended K (Kindness). First attested / used by the festival-going parents of a child who, upon realizing their child would adopt their expletives, decided to censor themselves with an equally effective-sounding substitute. The term has since been adopted as a playful alternative to vulgar expletives, maintaining the phonetic punch of taboo words without their profanity.
