BFB

BEST FUCKIN BITCH... your best friend, A-1 since day one. True ride or die. Unconditional sisterhood. The one who you can always depend on, no matter what the circumstances. True bond that lasts a lifetime. Closer to you than a "bestie".

Those two girls are inseparable because they are BFB's

She's better than a bestie, she's my BFB!
