a twitter group known for their bitchy tweets and is abbreviated as bsb. The group started in the summer of 2012 after a member made a type for "baker street", and continues to today. commonly obsessed with one direction, bbc dramas, and supernatural, this group will not allow others to join. Although some aspects of the group may seem fun, this is not a group to get involved with. the group fights occasionally but supports each other. they are gutsy and rude.
"hey who are those people talking about fanfic?"
"oh just some backer street bitches"
