BB
BB - Blood Brother, i.e. somone that is a really good friend and makes you laugh so that wee and sometimes sex wee comes out, but isnt an actual brother you just wish he was because he would make the most pwnage brother ever! You can always rely on your BB to make you laugh and you can trust them with anything cos they pwn hard ass.
"Hey look at Tom and Luke...they be such BB it be so cool, wish we could be like them. They set a good example for the whole world and will make a mansion where there is no judgement and everyone lives as equals because the world we live in today sucks ass."

Like the male version of Bonnie and Clyde...its B-B 4 L mofo (Blood-Brothers For Life Motherfucker)
