Fuck Yeah, Bitch (FYB)

Fuck Yeah, Bitch (FYB)

/fuhk yeah bich/
Noun, exclamation, lifestyle

Definition:
A euphoric, defiant expression of celebration, unity, and wild energy. Often exclaimed during moments of pure hype, spontaneous joy, or collective chaos. Originating in a Tusi Latino after-party dungeon in early spring 2025, “Fuck Yeah, Bitch” quickly transcended the underground, echoing through Brooklyn warehouses and beyond. Its rise to notoriety was fueled by Canadians, a Bronx-born Puerto Rican queen, and a women who dared to question why everyone was yelling it—and then joined in.

Now a movement, FYB has become more than just a phrase. It’s an ethos. A study. A science. A lifestyle. Some call it Fuck Yeah Biology, the academic pursuit of peak hype frequency.

Synonyms: Let’s f*cking go, hell yeah, viva la chaos
