"Pwned" means "to be utterly¹ defeated by an opponent" or "to be defeated by a superior power". 

“Pwned”（一败涂地）是“被对手彻底打败”或“被一股超强力量击败”的意思。

 

This informal term is used more often in video gaming, and supposedly resulted from a common mistyping of own with this sense, as a result of the proximity² of p and o on a computer keyboard. Along with pwned comes pwnage, being "the action or fact of utterly defeating an opponent or rival"

这个词属于非正式用语，常用于电子游戏中，据说这个词来源于常见的“own”误输，因为电脑键盘上p和o离得很近。和“pwned”一起的还有“pwnage”，意思是“把对手打得永无翻身之日的行为或事实”。

 

It can be pronounced as "owned" or as "poned", with both pronunciations being correct. In some cases, you will even hear it pronounced as "pawned³".

这个词可以读成"owned" 或"poned"，两种读法都对，有时你甚至会听到有人将其念做"pawned"。
