Mathsplaining 

When a mathematically capable person explains a math problem to a less mathematically capable person, typically in a manner regarded as condescending or patronising. Like mansplaining, except that it actually exists.

Math HL student: "Uh, you can't get the square root out of a negative number. Unless you're using irrationals"
Math studies student: "Stop mathsplaining to me!"

Mathsplaining

When someone suddenly pulls you aside and starts writing math equations and proofs to explain something you had only casually chatted about and really didn't need to know that much about.

I was just here for the free food, but this guy ended up mathsplaining to me for an hour

Mannsplaining 

The gritted teeth repetition of facts from a scientist forced to contend with the myths of morons all the livelong day.

"Michael's having a bad day on Twitter; he's gonna graduate from Mannsplaining to murder pretty soon."

Maxsplaining 

When you trap your life long formula one rival in order to explain every little detail about your race or quali session to them without a chance of escape.

Not to be confused with Mansplaining, while similar, Maxsplaining presents clear homoerotic undertones and heart eyes from both parties involved.

person 1: where's Charles?
person 2: oh, Max got him, he already started the maxsplaining
person 1: damn, that's a shame, there's no saving him now...

Meta-Mansplaining 

When frustrated manly men go and flood the Urban Dictionary with their definitions of the word Mansplaining, because they know it better than the feminists, actually.

Greg is so pissed off because his professor didn't want to hear him explain her area of expertise to her in his opinion, so he went meta-mansplaining in UD and invited all his friends too. (See mansplaining )

Mansplaining 

When a man explains something to a woman in a patronizing tone as if the woman is too emotional and illogical to understand.

"She got all pissed at me for no reason!" cried Ira, "Accusing me of mansplaining."
Aziz shook his head. "Women! Right?"

Mansplaining 

When unsolicited advice or direction is given to a woman by a man in a condescending manner. The reasons typically being, the man does not believe the woman is capable of completing the task independently and must need guidance.

"You're not doing that how I would do it so I'm going to bother you with my directions and opinions even though I am in no way a superior and you did not ask for clarification. There is no way you are capable of doing this by yourself and must be ignorant so you have to rely on my constant guidance."

"uh, I think I got it.. thanks."
