A chin with a dimple right in the middle that makes both the bottom left and the bottom right halves look like nuts. Typically found with hair just below these "nuts".
Dude Kevin, I havent seen you in a year! Whats up with those chin nuts man?
Used as an ice breaker or highvalue comedic punchline. Might raise some suspicion over sexuality if used improperly.

Guy 1: Stop playin'! This is serious!
Guy 2: ... These nuts were seriously on your chin.
