My attempt at defining anti-post :
An Anti-post is a type of meta-commentary or self-referential post that pokes fun at or satirizes the very format, medium, or conventions of the online community it is posted in. It often employs sarcasm, irony, and a reversal of the expected outcome or content to make a humorous point about the overuse, flaws, or tropes associated with a particular meme format or posting style within that community.
Anti-posts are not meant to be taken literally or seriously. Instead, they provide a self-aware, tongue-in-cheek critique of the community's own tendencies and common posting practices. By turning the format on its head or subverting the usual expectations, an Anti-post calls attention to the absurdity or repetitiveness of certain memes or posting styles that have become ubiquitous within that online space.
For example, in an online community where tier list memes ranking various topics (e.g. Linux distros) are common but often disliked for being subjective rather than based on facts, an Anti-post might create a deliberately ironic tier list that places the community's most hated topic (e.g. Microsoft) in the top "amazing" tier, while putting all the community's favorite topics in the bottom "bad" tier. The post would be framed as being "sponsored by" the hated topic, further emphasizing the sarcasm, self-referential and reversal of expectations.

By using sarcasm, irony, and a subversion of the usual format, Anti-posts provide a humorous, self-aware commentary on the community's own tendencies, tropes and inside jokes, often in an effort to point out their overuse or absurdity in a lighthearted way. They are a way for community members to poke fun at themselves and the conventions they have collectively embraced.
