At first, you’re like… BSF? Best snack friend? Big sister forever? Why do people keep using this? 😅
I remember the first time someone sent it to me, I stared at it for way too long before Googling it (and pretending I “totally knew” what it meant).
If you’ve been confused too, don’t worry — you’re not alone.
