People have been using pwned on a lot of youtube videos and i have NO clue what that even means?
Owned is standard English eg Bob owned a nice car (past tense)
pwned is hacker slang originally used in the context of successfully accessing a system eg Bob totally pwned that NASA server. It now (when used by civilians) has a general sense of getting one over on some one quite often by less than legal means.
As much as I dislike using Wikipedia as a source...
The word pwn most likely came about as a common typo of the word own because the "p" and "o" keys are adjacent on a standard English keyboard.
My gut feeling tells me that this fits the bill
In the context of the internet and video games, they are similar. Source
