Fantastic was a word used to describe something good or otherwise extraordinary. It was a term used frequently by the Ninth Doctor, as a catchphrase. (TV: Rose, et al.) Unlike the catchphrases of his successors, such as "Allons-y" or "Geronimo", "Fantastic" could be used in a sentence as well as being its own standalone statement.
