"Festy" describes anything that is dirty and/or smelly. It is particularly used to describe people, but may be used to refer to objects or animals.
Eew! You smell festy!
That guy is so festy.
I'm not touching that festy bandage.
Don't let your festy dog into my house.

Get the festymug. Those who frenquent renfaires as customers, often with seasons passes, but who are not part of the performing cast or otherwise work for the renfaire (ie. rennies). Usually some sort of badges are worn by workers and performers of a renfair as proof that they are employees. Because they add to the general atmosphere of a renfaire, most renfaires encourage festies to wear garb, thus creating the need for the badges to tell worker from patron.
They're not rennies, they're festies.

(noun) A person who lives to go to music festivals. A sort of lovechild of a hippie and a raver. Commonly sporting one or two dreadlocks and/or a partially shaved head. Loves face paint, henna, anything glow-in-the-dark, tattoos, music (especially dubstep, electronic, indie, folk, alternative), eastern/new age themed religions, hallucinogens and hula hoops. They generally refer to festivals as "home." Rainbow Gathering and Burning Man are the Meccas of festies.
Joanna and all of her festy friends rented a bus to drive to Burning Man.
Mitch: I can't even afford toilet paper, man. I bought tickets to Sasquatch, Coachella, Shambhala, AND Burning Man.
Joe: Dude, you're such a festy.
Mitch: What can I say. Festivals are home.
