Top Definition
A very rare and serious infection that starts in the penis. After your penis becomes fully infected, it spreads to the testicles and other areas. Some symptoms are itching, redness, rapid hair growth in the penis and testicle area, and burning. If you experience these symptoms you need to notify your doctor immediately.
My penis is burning! Maybe it's penisidus!
