Created in 2010 by actors Chloe Grace Moretz and Kodi Smit-McPhee, the word faboost means "fabulous" and is an in vogue replacement for the word "fab". Chloe Grace initially began usage of a word "faboos" to express this meaning, but Kodi suggested the addition of a "t" on the end when both he and Chloe Grace were being interviewed by lovefilm.com. Faboost went viral on Twitter very quickly.
My favorite film recently would have to be "Black Swan". It is faboost!
