    While it may not sound grammatically correct, a BSF here refers to someone with whom you are so close it feels like you’re practically siblings rather than just friends. “Sister’ and “sibling” are interchangeable here, but both pretty much get the message across that you all are basically inseparable.

    It appears that BFF (best friend forever) and BFFL (best friend for life) have met their match with this new abbreviation. Although, BSF seems to more often refer to a friend you feel is more like a sibling, similar to the “best sister/sibling friend” definition. Nevertheless, using BSF simply to mean “best friend” is totally acceptable. [1]
    • You might also see it stylized as IBSF, which means “internet best friend,” or someone you met over the internet through something like online gaming, a forum, or any other social media who became your friend.

    This is a clever way to turn the conversation towards a new topic or get back on track if you find yourself getting lost in the endless spam of messages coming from your friends or family. It’s usually used to bring the conversation back to the main point after a joke or lighthearted comment was made, and will definitely catch everyone’s attention. [2]

    It’s easy to go off on random tangents, especially when you’re in a group chat with lots of people who all have different things to say. If you want to circle back to a point that’s pretty much gotten lost in the slew of messages, get everyone’s attention with these three letters.
    • “🙋BSF can we get back to what we were originally talking about?”
    • “BSF are we actually going to ignore the fact that no one passed that test?👀”
