""I am going to be super-vague about what this secret is in reference to, but drop obnoxious little 'go on; I dare you to guess what it is!"

Sorta like the thing going on in the assumptions thread. The anon basically said they think someone is a fake/attention seeking but they're refusing to say who it is because "that would be mean". (It was fucking mean to start with but this vagueness just makes it extra mean IMO)
