A mans ball sack or penis that is decorated with jewelry from piercings that make it look rather Festive.

Types of male piercings: Ampallang, Apadravya, Cleopatra, Dydoe, Frenum, Guiche, Hafada, Prince Albert, & Trans-Scrotal Piercing.
At the gay bar the new way to ask another male if he is pierced down there is to ask if they have a "Festi Testi".
