A Festival of testicles!
Guy 1: Hey good looking I'm having a festicle at my house tonight do you wanna come?

Guy 2: No dude I'm not gay I don't like testicles!
A festering Testicle. Usually attatched to a dead body, the festicle is symptomised by its green, and somewhat soggy appearance. The festicle may also occur on a living male. Usually after the insertion of testicles into another persons mouth. see teabag.
1.) As i went to pierce guy's scrotum, i realised he had a festicle.

2.) As Guy walked down the street he felt something roll down his leg, and realised his festicle had fallen onto the sidewalk.

see scooter,fester. A form of human who can survive only on Dr. Skipper, 7-Eleven nachos and tri-tip. Commonly flanked by a pair of agressive, poorly trained dogs, festicles are often found sleeping on couches and drinking large amounts of ny-quil. Festicles are possibly best known for their ability to make large amounts of money disappear in a relatively short period of time at a roulette table.
There's a festicle sleeping on my couch again.
