What is bb meaning in text from a girl?

As an AI language model, I cannot answer this question with complete accuracy because BB can have different meanings depending on how it is used and the context of the message. However, here are some possible interpretations:

• BB can be a term of endearment used to refer to someone as a baby or sweetie.
• BB can stand for "bye-bye" used to indicate that the conversation is over.
• BB can also mean "big brother," used to refer to an older male sibling or a close, protective male friend.
• BB can also stand for "BlackBerry," which is a type of mobile phone often used for texting.
