In the ever-evolving world of social media slang, TikTok has become a breeding ground for new abbreviations and acronyms that sometimes leave users confused. One such acronym that has gained significant popularity is “BSF.” If you’ve been scrolling through TikTok and repeatedly encountered this term without understanding its meaning, you’re not alone. This article will break down what BSF means on TikTok, how it’s used, and why it has become such a popular term on the platform.
The Definition of BSF on TikTok
On TikTok, BSF stands for “Best Friend Sister” or “Best Friends Sister.” This abbreviation is commonly used to refer to someone who is so close to you that they’re considered family, even though you may not be related by blood. The term represents a relationship that goes beyond standard friendship, indicating a deep bond similar to sisterhood.
How BSF Differs from BFF
While scrolling through social media, you might have encountered both BSF and BFF. Though they sound similar, they represent different relationship dynamics:
- BFF: Best Friends Forever – a traditional term used to describe a close, long-lasting friendship

The distinction is subtle but important in understanding the depth of the relationship being described when someone refers to their “BSF” on TikTok.
