"zomgowned" is a "ZOMG"+"OWNED" combination, usually also pronounced as one word. It is basically both of the definitions together, "ZOMG" as a laughing "Oh my god!" and "OWNED" as "you've just been humiliated".
The Nintendo Wii manual's kid got punched by his friend tossing the Wiimote - ZOMGOWNED.
