leftsplaining 

The act when a person on the political left speaks over your point or a nuanced distinction you are trying to make, in order to inform you of “the correct” (and ostensibly only) way to model an opinion on an issue - according to the church of social justice.

When a social justice activist corrects another liberal’s attempt to critically think through an issue, or apply data, evidence and reason to come to a thoughtful conclusion (that doesn’t see all issues in binary, dogmatic terms) - by condescendingly informing them of the correct way to automate any conclusions on this matter in order to signal allyship.
“When I mentioned that I had seen pretty comprehensive data from numerous, reliable sources showing that the problem was not as far-reaching as constant media coverage seemed to suggest, Amber completely ignored my point and started leftsplaining how questioning *any* statements made by PoC only helps to reinforce the cisheteropatriarchy, and shouldn’t be entertained by anyone who is a good LGBTQ ally.”

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.
