An organization or group of people who regularly practice shenanigans in every day life. Typically anyone can become a Shenaniganian, but rigorous testing and many trials await to determine if someone is worthy of such a title.
Dude 1: "Hey, you're so full of shenanigans that you might be considered a Shenaniganian."
Andy: Did you seriously just give that kid a pixie stick? He has ADHD already!
Matthew: Awh crap.
Andy: *sigh* Now he'll be even more shenanigianous...
