It’s from the anime Naruto, it means you have insane powers to cast illusions so real that (for example) if you get stabbed your brain is so convinced that you got stabbed that you actually get a stab wound, and that’s not even covering the inhuman reaction time, the ability to copy anything your opponent does, and advanced techniques include black fire that never extinguishes.
And yes, I’m a huge nerd. I can’t call myself a weeb because I’ve only seen one anime.
