A third leg

A man with a penis that could pass for a third walking leg. It is long and full with a mind of its own.

He was short but he surely had a third leg based on the way his pants were positioned.

Restless third-leg syndrome

1. The inability to control one's penis, and, therefore fucking everything in sight. Generally it is men who are afflicted with this disease.
2. An excuse whoring men give for being unfaithful.

"Baby, it's not my fault you caught me with the Maytag repair man in a 69! It's my Restless third-leg syndrome acting up".

third leg

An unreliable appendage found on males of upright-walking species. More prolifent in warmer areas, especially in the native tribes of Africa, this appendage is not often used for mobility. The original third leg lost its foot in a shoe thousands of years ago and now all later third legs constantly search in shoes for the long-lost foot. The third leg becomes excited when it approaches the shoe found in between the legs of the female of the species, or the boot found on the posterior end of either the male or female of the species. The leg pokes around the shoe or boot looking for its lost foot, and culminates its search by spewing its tendons into the shoe or boot, trying in a last-stitch effort to reconnect the foot.

In prison, the larger males spend most of their time searching for their foots with their third leg for hours among other inmates.
