A Purity Beard is a beard a man grows until he is married, and on his honeymoon, his wife is then allowed to clipper and shave his beard off. It is the ultimate beardly sacrifice a man can make.
I'm sure all of you have heard of a purity ring... Its a ring people wear to declare abstinence until marriage. Well my idea is the "Purity Beard." Its when a dude (or girl if she can and wants too, I suppose) grows his beard out until he is married and let's his wife clipper his beard off on their honeymoon, making the ultimately beardly sacrifice.
