What Does ‘BSF’ Mean On TikTok?

What does ‘BSF’ mean?

‘BSF’ replaced ‘BFF’, which stands for ‘Best Friends Forever’. ‘BSF’, on the other hand, shortened the label to ‘Best Friend’.

While ‘Best Friend’ is the most used definition of this acronym, ‘BSF’ could also mean:

  • ‘Best Sister Friend’ – Not an actual biological sister, this refers to a friend who is as close as a sister.
  • ‘But Seriously Folks’ – Used after a joke or light-hearted quip to re-direct attention to the serious aspect of the content or conversation.
  • ‘BBSF’ is very similar to ‘BSF’ – ‘Big Best Sisters Forever’ is a self-explanatory variation of ‘BSF’.
  • Another similar spin-off on ‘BSF’ is ‘IBSF’- This refers to an ‘Internet Best Friend’, someone you met online that has become a close friend.
