The Dictionary of Information Science and Technology is the premier, comprehensive reference source compiled of the latest terms and definitions related to all aspects of the information science and technology field. This complete and timely collection of approximately 10,000 terms and acronyms provides researchers, practitioners, educators, and students with the most accurate and up-to-date knowledge of keywords in the ever-expanding world of information science and technology. Terms and definitions included in this important reference publication were contributed by over 2,500 noted researchers from over 40 countries. There is no single definition in existence for each element of the vocabulary, so individual researchers have formed distinctive descriptions of the terminology, providing a much more meaningful and broader understanding of each term.
Urban Dictionary is a slang dictionary with your definitions. "Urban Dictionary: a self-edited online resource, but unlike Wikipedia, it allows for many truths, rather than one authoritative guide."
I found it "googling" and it is very good. You can find words you just don't find in any other dictionaries.
