A filing cabinet is formal term for a person that exhibits little to no intelligence, provided that they have a functioning brain. Many people mistakenly use terms like "stupid", "retarded" or "mentally handicapped" in place of such a word, but those words are reserved for people without a fully functioning brain.
1. (of a performance) very intensely fah-bulous, usually impromptu, solo piece
Even though it deviates from the planned performance, neither the fellow performers nor the audience/viewers object, because it enhances the original performance.
2. incredibly good, unbelievably good, defies expectations with how fabulous it is, utterly fah-bulous
Christine: That guitar sesh in the outro was foilissimo!
M: Oh you mean how he went off-script when he started jamming with his guitar but it only made the performance more incredible?
Christine: Yes! And also how utterly fah-bulous the actual jam was!
Dona: Foilissimo indeed!
Ex-governor of Alaska and ex-vice presidential canidate who refuses to just fade away quitely- what with her book tours, TV deals, and that stupid "tea party". Continues to voice her opinion on everything as if her opinion really matters anymore.
Why won't Failin' Palin just shut up and go away already! She didn't win the vice presidency (thank goodness) and she's not even a governor anymore.
