It is an alternate version of the word "pwnt" which is derived from a scientific calculates code for standard deviation which is "xon".
To be x0nz0red is similiar to being "pwnt". (See pwnt)
The best way to deliver a x0nz0ricon is to use German language such as "Ich bien x0nz0red" roughly translated "I have been x0nz0red".
A common phrase to use is "Looks like youuuuuuuuuuuuu just got XONZOR3D." when something happens to another person, no matter how trivial it may seem.
Steven: Ich bien x0nz0red!
Steven: I fail at life!
