Interesting new words

Well, are there any new (English) words around that I should know about?

(Arthur already invented a new one).

Is it word “Artsie Fartsie” also used in the UK? It means you pretend to know something about “arts” (snobbish), but actually you are just an idiot! We also use this word to laugh with the Belgian leftist intellectuals (Really, I’m not one 😀 Quite the opposite :D)
