A post in a forum that is meant to look serious, but is actually satirical or ironic. Many people often cannot discern fakeposts from 'real' posts and thus they miss the joke. For the lack of a better analogy, pretty much everything Stephen Colbert says on the Colbert Report is the IRL equivalent of a fakepost.
I want to make fun of this guy, but he might just be fakeposting.
