look up any word, like bias:
A chin that juts out in one direction that slightly resembles a penis.
Dude, that chicks penis chin made it so hard to make out.

a chin that has a vertical crease or clef in it, but not quite a dimple. so it kinda looks like the head of a penis. a rare find.
That's not a dimple! It's definitely a penis chin.
