I should really call Luke, Pat, and Austin. We haven't festered in a long while, and I'm craving a cigar and a corndog.

A fester is someone who can be found at a festival of any type, regardless of the nature of said festival. You can identify a fester by the frisbees or nerf footballs they are commonly seen with in the parking lot of the fest.

An interesting fact about festers is that they procreate by biting non festers and injecting them with unholy fester venom. WATCH OUT!
Example:

Non Fester: Hey dude, what bands are you here to see?

Fester: Bands? Naw dude, I'm just here for the <i>fest</i>!
