Rather than typing "OWNED", the most common typo is "PWNED". By using "PWNED" rather than "OWNED", one gives the impression that the word was typed rather quickly.
"PWNED" is very often used by today's teenagers, the internet generation. The fact that froggie used it shows that, even though he is married, he is really a little kid trying to impress the easily impressed (AKA EvC-ers).
