The 'Hitler Particles' meme is a surreal piece of internet irony that originated within niche political and gaming communities, notably linked to the 'The New Order' (TNO) mod for Hearts of Iron IV. The meme typically features an image of a detector or Geiger counter reacting to supposedly 'evil' or 'fascist' energy emitted by a person or a statement. It gained mainstream traction on platforms like Twitter and Reddit as a hyperbolic way to mock someone’s controversial or edgy takes. By framing a subjective opinion as a measurable scientific phenomenon, users employ the template to sarcastically signal when a situation has reached peak internet toxicity or 'main character' energy.
