OOMF
OOMF stands for 'one of my followers' (or 'one of my friends'): a way to reference a specific follower without naming them. 'Oomf just said the wildest thing' discusses someone in your network anonymously, knowing they may see it.
Why it matters
Oomf is subtweet infrastructure: it lets users discuss followers indirectly, which drives a distinctive genre of anonymous commentary and call-outs. Recognizing it clarifies who vague posts are about, someone in the poster's own audience.
How it is used
Used as an anonymous singular ('oomf is being weird today'), often in subtweets the subject is expected to recognize. Plural: 'oomfs'. Common on X and in fandom spaces alongside 'moots'; the anonymity is often deliberately thin.
Frequently asked questions
What does oomf mean on Twitter/X?
'One of my followers/friends': an anonymous reference to a specific person in the poster's network, usually in commentary they will likely see.
What is the difference between oomf and moots?
Moots names the mutual-follow relationship; oomf anonymously references one specific follower. An oomf may or may not be a moot.
Why do people say oomf instead of naming someone?
Plausible deniability: it discusses someone without tagging them, softening a call-out or compliment while often intending them to recognize themselves.
