What does "P&S" and "Owned or pwned" mean?

Answer 1

P&S I have no idea, could mean anything really.
About "owned" here you have it (from wikipedia)

"Owned" (often typed in leet speak among gamers) is an internet slang word used commonly in gaming circles to acknowledge a form of superiority through the downfall of another entity, be it another gaming clan, or a single user. This can be in the context of winning an online game, a debate on a forum, or attaining a successful hacking, as well as the signature to a rebuttal, such as "You got owned!" to announce the defeat of another user on the internet in the form of a debate or flame war. It signifies screwing up and humiliation, often through the dominance or superiority of another party. Usually, the term is used to express dominance in a negative sense, proclaiming better skill than the opponent for purposes of killing them. "Owned" can be used as both a verb (to "own") and noun ("ownage").

While sometimes similar in usage and pronunciation, "owned" is not to be confused with pwned, which many consider an entirely different term.

Ownage has recently spread beyond the gaming community into standard slang, where it ususually means severe defeat (eg when a person in an argument is so soundly beaten they are lost for words) or when someone is injured/defeated/etc in an amusing way. The term "own" may also refer to "coolness".

Answer 2

I think it means that you have been beaten badly at something like in a game like if you keep killing a guy in the same game over and over again that i think would be considered owned
