Iransplaining

When non-Iranians speak over, dismiss, or reinterpret Iranian voices and lived experiences—often while positioning themselves as more informed or authoritative on issues that directly affect Iranians.
“Every time Iranians share what’s happening, some “activists” jumps in to correct them with headlines they barely understand. That’s straight-up Iransplaining.”

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
