What is a shitpost?

I think I can get the idea. But could you provide an example from him?

A shitpost is hard to classify, but it is usually an off-topic post intended to derail, hijack, circlejerk, or otherwise spam a conversation.

I don't have any examples of Palmer shitposting, because his scheme never really got off the ground. A generic example of a shitpost would be if say, someone posted in this thread this image: http://i.imgur.com/QoZHVLs.jpg and demanded that we only post spiderman memes, instead of talking about the intended topic.

It's just a term referring to a shitty post.

More "worthless" than "shitty".

Some people call posting humorous nonsense on Facebook or Twitter as "shitposting" as well. Doesn't add anything, but can be amusing in small doses.

As you can see from your replies, it has more than one definition depending on where on the internet you are.

All of the examples you've been given are hilariously wrong. 'Shitposting' is a play on the idea that people with non-pc views are 'shitlords.' It grew out of groups like "Shit Reddit Says" and "Shit 4chan Says" that meant to police language on those sites. tl;dr A "shitpost" is a post that's not politically correct.

Shitposting is just making terrible posts. That could be posting lame stuff, making the same sort of post that is always made on those sites, or just being a nuisance spamming.

Just like the way pepe the frog changed. The connotations around shitposting changed.

Noooo. The term shitposting significantly predates SRS. Please see the Know Your Meme entry on it for more info.

No. Shitposting is making terrible posts. Low quality, dumb low effort, etc...
