Someone who has gone way beyond their fifteen minutes of fame into becoming
omnipresent in every corner of social media, when they became famous for something that shouldn't be bragged about, i.e., a sex tape, reality show, etc., or is a wannabe who aspires to being such by whoring themselves out (figuratively or literally) to get attention.
It can also be used in connection with movie remakes or
sequels that have outlived their original
entertainment value.
Jim: "How about going to the new
Pirates of the Caribbean movie tonight?"
Jane: "I love Johnny, but that franchise has become too Kartrashianed for my taste! In fact, I understand that 2011 has the most
sequels ever released- a total Kartrashian year!"
Sue:"Are you watching the new reality series set in Dallas?"
Anne: "Hell no! Yet another group of Kartrashians looking for some
big break!"
