look up any word, like thot:
 
1.
Beard rub: A formal greeting or display of manly solidarity between two or more bearded men.

Can also be called a scruff hug, or a beard-bump. Commonly used for novelty, or to show that you, as a bearded man, are not fucking around. Beards are highly dangerous and anyone who attempts to use and/or get near one risks serious injury and/or death. Beard at your own risk.
Beard Rub happens when 2 or more suitably bearded men meet up and rub face.
