The state of which living fungus is actively growing on a human male's reproductive organ, the penis.
Matthew was working in his tool shed on a new cage for his chicken coupe. All the sudden he had the strong urge to itch at his crotch. After minutes of scratching at his dick, his jeans being the middleman, he slid down his pants only to see a glowly green shine from his penis. The glow was extraordinarily bright, and after a couple minutes he could have sworn it started to move vibrantly around his 2 inch cock. Matthew has a bad case of Dick Fungi.
