Sorry oristarA, no dice. If your dictionary is not at fault, your understanding of it is very much incorrect.
It is not slang, it simply makes no sense -- there's a big difference.
By the way, a slang dictionary you might find useful in the future is
www.urbandictionary.com (keep in mind, though, that definitions are sent in by users, and quality control is somewhat limited).
