The term w00t (spelled with double-zero, "00"), or woot, is a slang interjection 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.
