mutton chops

Sideburns that are narrow near the ear but broad and rounded near the chin, forming the shape of a mutton chop.

Mutton chops often look like a beard without hair on the chin (Danbooru post #2560565), or stretch down past the cheeks and into a mustache (Danbooru post #3671798). In the latter case, they are known as friendly_mutton_chops.
