A mole goatee is a condition that develops when a person with a hairy mole doesn't attempt to cut the length of the hair, manicuring it to be more like a traditional chin goatee. Furthermore, the molehair that comprises a chin goatee will many times appear to have pube-like characteristics.
"Dude, the attendant at the corner jiffy mart had an insane mole goatee going on. The hair was about an inch long and nearly hid his mole. I wanted to grab him by it and yell "What in the fuck are you doing man? Shave that shit, no one wants to see that" said the college student.
