Bearded Nelson

Someone who attempts to grow facial hair while being physically unable to grow a complete, bushy bear-like beard, and instead sports what is best descirbed as 'peach fuzz'.
This person is usually fairly young, and should probably wait a few years before tying to sport facial hair again.

This look us often paired with a mullet.

Friend 1: Hey look at that guy over there, he can't even grow a proper beard like a real man.
Friend 2: Yeah that is a proper bearded Nelson, mate.
