Update README.md

Had to revamp this because I that old code made me think of other things...
- bb is a droid on Star Wars
- bm is bowel movement
- bs is... well, you get the idea.

New expression for b allows for multiple areas to be defined for hair growth

 ### b – beardliness/facial hair
 As facial hair plays some sort of role in geek space, serving as an expression of style, countercultural proclivities, etc. etc. and [unix beards](http://www.usenix.org.uk/content/unix_beards.html) being a thing we give it a category here despite its irrelevance to some fraction of the population.
 
+The hair code is divided into 5 parts, delimited by a colon. The parts are (head:beard:brows:mustache:sideburns)
+
 ```
-b 	=	beard
-bm 	=	mustache
-bs 	=	sideburns
-bb 	=	bushy eyebrows
++++	=	Some people look at me and think I'm Sasquatch I have so much hair
+++		=	Amazing hair growth!
++		=	Some hair growth
+		=	Average
+-		=	Less than normal, partially shaved
+--		=	Bald / Shaved
+---	=	Alopecia / Unable to grow hair there
 ```
-Thus b++/bm++ means impressive beard with equally consequential mustachio. Leave blank for no facial hair.

+Thus b_:++:+:++:_ means that geek has an average head of hair, with an impressive beard, thick brows, an equally impressive mustachio, and ordinary sideburns.
