BFSK

An annoying abbrieviation for “Best Friends Since Kindergarten” that only annoying, white girls use on social media excessively to encourage questions about it for attention.

Annoying white girl: Omg my BFSK is coming over! She’s my BFSK and we are going to do BFSK things together because we are BFSKs.

Everyone else: shut the fuck up.
