execusplain 

Very similar to mansplaining where an executive delivers a completely inaccurate description of a topic, with complete confidence that he or she's right. The big problem with execusplaining is that the executive is delivering the nonsense to subordinates, they are loath to disagree for fear of getting fired.

Even though most of his team had already worked at high-tech startups, the VP felt the need to execusplain how startups build products.

Execsplain

When an executive authoritatively explains basic concepts to non-executives to mask the absence of proficiency in their job. Often delivered in a condescending way, so as to provoke an emotional response, thereby shifting blame to the audience, further obfuscating their lack of qualifications.

Did you hear the CMO execsplain Github to those engineers? I wonder if they have any work to do?

Excuseplaination 

An explanation which is simultaneously being used as an alibi, which although it is valid was not necessary to say as an explanation for any reason other than as an excuse.

"That's a crappy excuseplaination bro."

Excusplanation

When you're asking someone for an explanation but all they ever give you is excuses.

Boyfriend : look, can we please just talk about what happened later?

Girlfriend: Yes, and I can't wait to hear your excusplanation about it.

Boyfriend : what's wrong? Why are you mad? What did I do wrong?
Girlfriend : everything! Please explain this <insert whatever made you mad here> to me!
Boyfriend: it wasn't me! I didn't do it! I don't know how it happened! I would never do that! I wouldn't lie! Please believe me even though I can't explain anything ever at anytime nor do I have to because I'm innocent!

Girlfriend: of course, i should have known. More empty excusplanations.
