Woot is an interjection similar to "YAYE!" or "Woohoo!" used to express joy or excitement, usually about some kind of accomplishment. Primarily used by gamers, spreading rapidly to anyone who chats online.

Woot是跟“耶!”或“噢吼!”等感叹词类似一个词，多用来表达欣喜或兴奋之情(网友多用“狂喜”二字解释woot)，而且多在取得成就时使用。这个词最初只是游戏玩家常用，后来又迅速传播到网聊人群当中。

Woot originated as a hacker term for root (or administrative) access to a computer. However, with the term as coincides with the gamer term, "w00t", which was originally a truncated expression common among players of Dungeons and Dragons tabletop role-playing game for "Wow, loot!" Thus the term passed into the net-culture where it thrived in video game communities and lost its original meaning and is used simply as a term of excitement.

Woot这个词本来是黑客用语，指电脑的根登入系统(即管理员登入系统)。不过，因为跟游戏用语w00t外形相似，才得以在网络文化中传播，兴起于视频游戏圈，之后脱离其原意而成为单纯用来表示兴奋之情的一个感叹词。游戏用语w00t是桌面角色扮演游戏《龙与地下城》的玩家常用的一个词，是“Wow, loot!”(喔，赢了!)这两个词的缩略形式。

For example:

I defeated the dark sorcerer! Woot!

我大败了黑巫师!耶!
