The act of mutual anilingus (ass eating) between man and woman, typically
husband and wife. Named for Paul Bernardo and Karla Homolka, the Barbie and Ken killers. Paul referred to Karla as his “little
ass licker” and there is a picture of them holding two
alcoholic beverages while drunk; presumably, one would think they toasted the drinks, creating a “klink” sound, thus “klinkies”.
