Will people please consider a moment's thought before using this adolescent phrase? People throwing it around are probably not using it with its most precise and defensible meaning (a la Harry Frankfurt). So the most charitable alternative gloss is that it's used carelessly to mean someone is just wrong. It's a very poor (because ambiguous) word choice for that. I suspect it's usually deployed to suggest someone is lying, for which you need specific evidence beyond believing a statement to be incorrect. That evidence is very rarely available in an HN comment.
It's hard to be thoughtful about using language, and I'm no exemplar. But a good start is just avoiding reflexively spitting out some rarely useful prefabricated phrases. This is one.
