A former member of the site, Adz, broke the rules and insulted people many times. It came to the point of which "adz" could be used as a word, meaning, 1. anyone who acted in a way Adz did, 2. anyone that you have suspicions against, 3. or a word to be added for emphasis.
Not to be confused with the carpentry tool (also called "adz")
This guy is sending me spam. He must be adz.
This adz-fucking thing is so fucking adz.
