3BC 

three B's and one C
Bothell Boys Basketball Club is one definition as the school would like to say...

however the real definition is
Bothell Boys Brew Crew

3BC goes on shirts and you get nick names on the back, usually inside jokes that are inappropriate.

person 1: what are you getting on your 3BC shirt this year?
person 2: i dont know, i think i'm going to get "insert inside joke here"
