BSF meaning on TikTok

On TikTok, BSF stands for ‘Best Friend,‘ and it has become increasingly popular on the app, with users including the term in videos, comment sections, and direct messages. For many young people, it’s even replaced the acronym BFF, which stands for ‘Best Friends Forever.’

When a TikToker dedicates a post to their best friend, they would often add the term either in the caption or in the text overlay. BSF has also become a widely used hashtag on the platform that users include in their videos to show appreciation and love for their closest friends.

Although ‘Best Friend’ is the most used definition of this acronym, BSF could also mean ‘Best Sister Friend,’ which refers to a friend who is as close as a sister. However, the former definition is generally more common.
