raise!" Often used for small victories the speaker dies not expect to
be of special interest to anyone else. Some claim this is a
bastardization of "root", the highest level of access to a system
(particularly UNIX), originated by script kiddies as a 133tspeak
equivalent of "root", and said as an exclamation upon gaining root
access. Others claim it originated in the Everquest multiplayer game
as an abbreviation of "wonderful loot". Still other claim it on
originated on IRC as the "Ewok victory cheer"] Adj. w00table has the
sense of "cool" or "nifty". This is one of the few leet-speak coinages
to have crossed over into non-ironic use among hackers.
