Your BFF might use LBF to mean "later, best friend." You're most likely to encounter this sign-off at the end of a chat or text conversation, when you're speaking with a very good friend.
If you receive LBF from someone who you do not consider your best friend, you may want to inform them of their current status re: your friendship. Or, you may want to just let the person continue living their fantasy. After all, everyone should have a best friend.
