What does FBF mean in dating?

Could you please clarify what "FBF" stands for in the context of dating? Is it a common acronym or slang term used in the modern dating landscape? I'm curious to know if it represents a specific dating strategy, a type of partner preference, or perhaps a trending dating concept. Understanding this term could help me navigate the sometimes confusing landscape of modern dating and relationships. Any insights or clarifications you can provide would be greatly appreciated.
