Ich hab' einen Anfänger platt gemacht!

The english wikipedia has a fairly good article about this word.
In deed the origin of the word is "own"

"dominiert" ginge auch; der Ausspruch soll ja Dominanz ausdrücken.

Meine Erfharung

Man benutzt dieses Wort,wenn man jemanden ''Weg haut''.Das heißt in klar Text : Ein fertig machen,Zerstören

@ #5: Hi! - Do I read you correctly, if I understand:

'Meine Erfahrung':
'Man benutzt dieses Wort, wenn man jemanden 'weghaut'.
Das heißt in Klartext : Einen fertig machen, zerstören'
? . . .

Qelle = Counter Strike

Ich denke mal pwned or pwnd however meint das man jemanden plattgemacht hat bzw gerolled hat xD^^

Game : Counterstrike

If you kill somebody in that game over and over again with just your pistol you owned him with your pistol and therefor you pwned him (pistol owned).

Kommt vor in dem Spiel Counterstrike.
Wird verwendet, wenn einer der Gegner immer und immer wieder mit einer Pistole zur Strecke gebracht wurde.

Besiegt, Platt gemacht, etc.

Mal ne Noobfrage: Wie wird das auf Englisch bzw. Deutsch ausgesprochen?

http://en.wikipedia.org/wiki/Pwn#Various_pron...
Even though the word pwn appears as early as 1989, because it is primarily used in written form only, it has no single accepted pronunciation. Common pronunciations include "pone", "pawn", "puh-own", "poon" and "pwen".

Pronunciation
Given the recent development of the word and its primary use in written form only, there is no single accepted pronunciation of pwn; as w does not typically represent vowels in English.
Use, online and in popular culture
Some popular quotes involving "pwn" include:
* The 2006 South Park episode, Make Love, Not Warcraft, satirized the game World of Warcraft. In the episode, the word is pronounced [poʊn] (pone), rhyming with "own".
* "Looks like you're about to get pwned. Yeah!" - Eric Cartman (20m 30s into episode)
* "That was such über-pwnage" - Kyle Broflovski (soon after above)
* In Teen Girl Squad, "PØwned" appears on the screen and is pronounced by Strong Bad as "Puh-owned! Or however you say that!" Later the derivative "P4wned" appears, referring to a pawnshop and is pronounced "Puh-awned".[4]
* During the telecast of the 2006 World Series of Poker Tournament of Champions, Daniel Negreanu tells Mike Matusow that Mike Sexton pwned ([poʊnd]; pond) Matusow with an especially good play. The closed-captioning, however, misinterpreted Negreanu's remark as "boned".
* The Internet TV show Pure Pwnage claims that the word is pronounced "own", as it was a spelling mistake in the first place.
* In the movie Employee of the Month, the character played by Dane Cook uses pwned (poned) during a competitive scene.
* The vodcast Bikini News, in their episode Guide To Getting Your Crappy Video Seen Online!!!, states that by following their advice, "You'll pwn all of us!".
* In popular Newgrounds series "Thwomps" Thwomp #1 can be heard saying "Pw3ed" (Pwinned).

@ 10: Das sagen Wikpedia und thefreedictionary.com.

I would go with Cartman from Southpark who is surely the most authoritative source of all ;-)
