A mash-up of the words "celebrity" and "retarded," the word celebutard refers to any of a crop of famous people (mostly young, mostly filthy rich) who are unable to form complete sentences in a public setting. In fact, they probably couldn't even grasp the concept that "celebutard" is made up of two separate words.
Did you see Paris/Jessica/Britney/Lindsey's interview in OK! Magazine? I was amazed at her erudition. Sike! She was a total celebutard.
A shameless female who prefers to stoop to the level of a crack-whore in a desperate attempt to attract any publicity rather than none.
This is often achieved by dressing as a slut when attending movie premieres or acting like a slut to gain attention at celebrity parties or attracting a male audience rather than no audience to an otherwise mind-numbingly boring TV show.
"Paris Hilton upstages host at celebrity party by performing lewd celebslut acts"
"Gwyneth Paltrow sports another disappearing celebslut dress at movie premiere"
"Nigella Lawson licks herself provocatively on screen like a celebslut rather than cook food on a TV cookery show which would otherwise attract a very low audience"
