Boss Chin is where you grow hair only on your chin. It is different than the "soul patch" because it is not located directly beneath the lower lip, and is not a goatee, because there is no hair in the mustache area. It does not grow below the neck, so it is not a beard, and does not extend wider than length of lips.
Dude, check out that boss chin! So cool!!

His girlfriend was tired of his goatee pricking her lips, but instead of shaving the whole thing off, he convinced her to let him keep a boss chin.
