Pawned

[Ernesto]

The word [pawned] is sometimes used for the exaggeration and boasting of a won [game of chess]. It can also be used by a player with a significantly advantageous position that feels the urge to taunt or [aggravate] his or her opponent.

[exinilu]

n. [pawn]

Something given as security for a loan; a pledge or guaranty.
The condition of being held as a pledge against [the payment] of a loan: jewels in pawn.
A person serving as security; a hostage.
The act of [pawning].

tr.v. [pawned], pawn·ing, pawns

To give or deposit (personal property) as security for the payment of money borrowed.
To risk; hazard: pawn ones honor.

Those are the proper definitions.
Now for [Pawnage] itself:
Defined as,

A [chess piece] of lowest value that may move forward one square at a time or two squares in the first move, capture other pieces only on a one-space [diagonal] forward move, and be promoted to any piece other than a king upon reaching the eighth rank.
A person or an entity used to further the purposes of another

In the second example, we can see how the idea of Pawnage can be used as a legitimate meaning behind [Pawned], Pwned, or otherwise. Those whom you own contribute to your score in games, your social status in person, or whatever else you can apply it to. Thus, youre using someone as a pawn for your overall benefit.

[Dorothey Allen]

Many people attack [pawned] as a misspelling of pwned, but it has, in fact, become an acceptable spelling. The original origin of the word pwn was a typo, probably from a [high-speed] chat, of the word own. Think how the is now teh in traditional [l337] internet slang. In any case, looking at the origins of the word own, one could [deduce] that it implies some dominance over something or someone. When own and owned became pwn, pwned and pwnage, the words came to mean the same thing; dominance and superiority. The new word [pawn] is very simmilar in the sense; its plain definition is to belittle or reduce someone or something to pawn status, essentially, owning them.
