Runsplaining 

The act of assuming a new member of your running club is new to the sport of running and minimizing their answers to questions about their background.

For example; if they say they haven't done any races in a while a runsplaining person may assume it's been a few years but maybe it's been just a few months. If they say they are not running as much as they used to, the runsplaining person may assume they are running a minimal amount when in fact it could still be serious mileage.
Them: Hey ! I've never seen you at our runs before. So, you just decided to get fit ?

Me: Yeah sure. Whatever makes you feel better about yourself.

****************************************
"I told them I haven't been running as much as I used to and they were runsplaining me. They said, "oh well, glad you're getting back into it."

"I didn't tell them I was running (x number of miles) and kicking butt. Oh well."

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.
