1.Beyond being pwned. It's simply the highest you can go, someone who seriously got burned/hit/shot/ran over/embarrassed to the knees. It's really that bad. Only used when necessary, otherwise simply just use pwned, this word should only be used in real life, and not in games.
2. Another way of saying pwned to someone. Some say the word was derived from the website title "pwned.nl"
3.Made up by a group of kids, who randomly started saying it one day instead of using "owned" or "pwned", it is thought to mean more than "just something".
