Incitatus is a term used to describe a man with a non-functioning, and oft-times small, penis. Derrived from the famous Greek eunuch incitales.

In the ARG community, incitatus is a common slang, used to insult someone who is being boasting about lies.
A very unsatisfied lady said to her new boyfriend, "That Chuck, he's such an incitatus!"

Stop blathering, you're being an incitatus!
