Groypers are crypto-fascists (fascists pretending to not be fascists), usually originating from /pol/, who call in to talk shows with initially innocent-sounding questions and then try to get the host to respond to increasingly aggressive
neo-Nazi talking points. The goal is not to win debates, but to bewilder the host and spread
neo-Nazi ideas to their audience.
They frequently engage in
trolling campaigns to try and shape public opinion in ways favorable to the far right. That includes barraging normies with conflicting information, similar to the many
fake definitions for "groyper" on this site.
It is unknown what groypers look like in real life, since they are highly averse to engaging with
reality in any way, but some theorists predict their physiology is similar to that of Vogons.
