A mix of fabulous and fanstic, used to express extreme appreciation and/or happiness. Most commonly used by over zealous flamboyant males turning ugly girls into beauty pageant queens in shows such as MADE.
Mixture of fantastic and fabulous. Makes one sound even more gay than "faaaboulouuuus!" But fun to say and describes something that has no negative aspects to it at all.
Derives from the word fabulous and fantastic. Basically a more fabulous way of saying something is fantastic. (Or vice versa, whatever tickles your fancy)

For when you can't decide whether to use "fabulous" or "fantastic". Just use them both. Why not? They mean the same thing.
Used in the same way as "fabulous" or "fantastic", only twice as excitedly.
