When someone has a prominent chin that gives the face a concave, banana-like appearance.

This quality can be considered unattractive and mannish in women.

It is the impediment of many male-to female transgender people, who often seek out facial reconstruction surgery to reduce the size of their chins.

It can be made less obvious by only taking selfies with the face pointed directly at the camera.
