The crook of all the beard styles. Very sparse and patchy, sometimes looks like a dirty shit pirate beard. Usually worn by metal heads or just ratty gnarly fucking dudes.

A rat beard is a haggard ass beard, that goes unshaven for many months. This beard is especially rat like due to the fact that it is repeatedly straightened.
