blood sisters

Oath-bound female friends

Blood sisters are women or girls who have sworn a bond of loyalty and sisterhood, traditionally by mixing their blood through a small cut, symbolizing that they are now connected as if by family.

The term emphasizes a chosen relationship as deep and permanent as biological kinship.

More loosely, blood sisters can simply mean close female friends who consider themselves family, without the literal ritual.

We became blood sisters in fifth grade, pricking our fingers behind the gym.
