devsplaining 

When a software developer explains why the application (formally known as, 'teh codes') acts in a certain way that is surprising to the non-technical user.

Often the engineer will accidentally come off as arrogant or boorish. This may be to compensate for the fact they are trying to pass off a bug as intended behavior.... or that they are just as confused by this behavior as the end-user.

parallel to mansplaining or mansplain

Delsplaining 

To Delsplain is to continually talk bullshit to a YouTube audience. Someone Delsplaining will generally be seen to make things up on the go. They usually have no knowledge of the subject they try to teach, they then do it in an unsafe manner.
Did you see that video of John mending his mobility scooter! He had no idea how to fit that wheel but as usual he just kept Delsplaining as usual. But hey you already knew that!

Displain 

Disrespectfully explaining. Unisex word for "mansplain". As women can also "mansplain" I though a unisex word for this world make sense, therefore: displain
"are you trying displaining that to me..?"
"people who displain think they're better than everyone else"

Word of the Day on October 4, 2026
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.

Pee Calculus

When you have to pee in a movie but don’t want to miss anything, and must do the following mental equation: will the amount I have to pee cause enough discomfort to diminish my attention capacity for the remainder of the movie to an extent which is greater than the amount of the movie I would miss by making a mad dash to the restroom.
I saw Satantango last night, wonderful film but by the 5th hour I had to start doing pee calculus.
