Also known as Butt Crack Boy. This acronym originated from a conversation a girl was having with a guy as they were
talking about being paid for services. A miraculous idea
popped into the guy's head as he tried putting money down her pants. As amazed as she was by his stupidity, she decided to establish a nickname for him known as BCB. The female version of the
name is called BCG, for Butt Crack Girl.
