On TikTok, Twitter, and Instagram, the slang “OOMF” is everywhere—but what does it actually mean? Short for “One Of My Followers,” OOMF is used to talk about someone online without naming them directly. Whether it’s a crush, a friend, or even someone causing drama, the term keeps things playful and vague. From flirty captions like “Lowkey, OOMF is kinda cute” to shady tweets such as “Can’t believe OOMF thinks we don’t notice,” it’s become a go-to way for Gen Z to share thoughts without oversharing.
