A chin that look like an arse (in some cases). In others, they can be very sexy and attractive. A nice facial feature (most of the time)

Bumchin is a term to describe a small young fat guy with a bit of a bum on his chin. He is known to hang round with General chode and chode kings prodigal son. He has declined my offer for an alcaholic beverage (bevvy) several times. Such a shame. Also dumped his first girlfriend after seeing her face.
