Adverb, Verb: An expression used in conjunction with the upward and outward swoop of the pointer finger. Commonly used in sarcastic suprise at a ridiculous comment or situation. More often used with a mocking tone, directed at a person who just made a terrible joke, or just told an endless story with no point at the end. Voom has also been used to salvage the forementioned endless story, used as an "ace in the hole." Though this usage of the word is only effective on a select (and easily amused) audience.
