To be pwned so hard that the only describable explanation for the ownage was that you were against Chuck Norris. This term is so strong that using it freely can cause loss of friends at an alarming rate. The actual occurance of people being norrissed is very small. According to recent studies, the amount of norrissings is equal to 10 times the number of total pwn10d's, which is in turn equal to 10 times the number of total pwn9's, etc. This makes it possible for the total amount of norrissings to be a decimal, which makes sense, since it is impossible for mortals to perform on a level equal to that of Chuck Norris.
The hierarchy looks like this:
Guy 1: dude, i just norrissed these guys on CS, i got a 1342 kill streak with my monitor turned off in a 141231 v 1 match while lagging
Guy 2: stfu ur full of it man, thats only a pwn7d at most, your not my friend anymore go die.
