much like a dirty sanchez, it is when fecal matter is applied to the face in such a way it covers the entire lower jaw and upper lip. it is also typically applied by pirates (homosexual or not) to other sleeping pirates/crewmates/scurvy dogs as a joke. it is punishable by having to walk the plank, getting the shit beaaten out of you, or recieving a brownbeard in an act of revenge from the victim.
"yaaaarrrrr, captain, i gave steve a brownbeard last night! he has no idea!" this is followed by plankwalking and "aaaars" of disapproval, or a hearty round of pirate laughter.

To receive a brownbeard, means that you have been performing oral on your sexual partner, when the partner decides to shit on your face, covering your chin and possibly more of your face. Brownbeards are typically received when the partner is suffering from explosive diarrhea.
'Oh my God I'm so embarrassed, when Jimmy was licking my ass I gave him a brownbeard'
'Hey baby why don't you give me a brownbeard tonight?'
