Gamers are known for using uncommon acronyms online like Poggers, OP, Instalock, and many others. This includes BSF which is heavily used by Roblox players, and here’s what it means.

Acronyms and slang like LOL, ROFL, SMH, and IKR, among countless others, are enough to explain the impact of the internet in the last decade. Every situation now has a perfect acronym and gamers use them too.

Roblox is all about creating games, sharing them, and playing them with friends. The platform thrives on community-driven games, and it is no surprise that the Roblox community which contains millions of players has its own terms and slang.

On that note, here’s what BSF means in Roblox.

All meanings of BSF in Roblox

BSF in Roblox is short for “Best Sister Friend” and “But seriously, folks.” Both the phrases are completely different from each other and naturally, are used in different scenarios.

What is a Best Sister Friend in Roblox

A Best Sister Friend (BSF) is a Roblox player who is as close to you as a sister. Simply put, this is a term to greet friends who are as close as family.

Accordingly, you might find many Roblox players calling each other’s BSF. Such friendships can be entirely virtual or the players might know each other in real life as well.

For some players, saying Best Sister Friend (BSF) is equivalent to saying Best Friend (BF). On the other end of the spectrum, there are players who believe that BSF is a special term and should not be used generally.

When to use BSF as “But seriously, folks” in Roblox

Although rarely, Roblox players use BSF during conversations to say “But seriously, folks.” This is a smart way to bring back the actual topic of a conversation if it fades away between jokes or other remarks.

It is evident that BSF is not a Roblox term that you should be worried about. The toxic faction of the player base uses some derogatory terms, but luckily, BSF is not one of them. It is either a wholesome way to greet a friend or a clever way to direct a conversation.
