The honorific that can mean solidarity or sarcasm depending entirely on your tone.

means An informal, affectionate term for a close female friend or sister, used as a form of address.

from Simply a clipped form of 'sister,' shortened the way close, frequent terms tend to wear down over time — the same instinct that turns 'brother' into 'bro.' It traveled from literal sisterhood into broader use as a warm, familiar address, especially prominent in Black American English and later absorbed into wider internet and youth slang, where its tone can flip from genuine warmth to pointed sarcasm depending entirely on delivery.
