The term w00t (spelled with double-zero, "00"), or woot, is a slanginterjection used to express happiness or excitement, usually over the Internet. The expression is most popular on forums, USENET posts, multiplayer computer games (especially first person shooters), IRC chats, and instant messages, though use in webpages of the World Wide Web is by no means uncommon. The spelling with double-zero "00" is similar to l33t text.
The definite origin of the term "w00t" is unknown but it has been seen early on in IRC chats. One theory claims that use of this term dates back to the mid-1990s, when it was probably derived from the alternative spellings of whoomp and whoot. These spellings are variously used in the phrases, "Whoomp, there it is", or "Whoot, there it is" from two songs in 1993 from rap groups Tag Team and 95 South, respectively. Another theory is that people started jokingly mimicking trains in children's books, that went "Woot! Woot!", doing so as a statement of victory, or applauding good news. (Some people today say "Woot! Woot!" while making the hand-gesture of pulling a train's horn cord.) Some people say it was just a parody on a child with a speech defect trying to say "loot" and saying "woot" instead. Others have theorized the term is an acronym for "We Owned the Other Team". It has also been alleged that "w00t" is a contraction of the phrase "woo, loot!" used in Dark Age of Camelot, "wonderous loot" used in Ultima Online and "Wonderful Loot" in Everquest whenever a player found large quantities of/or rare valuable items in game. W00t is also somewhat like the Scots word "hoots", which is used in a similar manner — an exclamation signifying surprise, disbelief, or kindred reaction. This is also along the line of some peoples use of "W00t?", replacing 'wot?' or 'what?' as a response to a happy surprise. Another supposed origin is as an expression used by a cracker (see security cracking) who has just broken into a computer system, obtaining "root" access: "woot, I have root!"
The word "w00t" itself was first seen in 1994. The expression rose in popularity in the late 1990s and early 2000s (decade) mostly on MMORPG such as RuneScape. It remains a niche Internet term and is not in general usage. The symbolic approximation of Latin letter forms makes w00t a prime example of internet leetspeak. It may also sometimes be seen spelled as "wewt" or "wought".
The word was featured on the list of Merriam-Webster's Words of the Year for 2007. They said, it "reflects a new direction in the American language led by a generation raised on video games and cell phone text-messaging".
Apart from the British digital sales house w00t!media the expression has also made it into an URL-shortener.Garaj Mahal named their 2008 album w00t.
