Tysplaining 

The act of mansplaining to not only women, but men as well. The individual committing the act believes he has a wealth of knowledge far beyond what he actually does. This includes subject areas in which the individual has absolutely no experience.

Caution, correcting the offender will have little to no affect on his behaviour and is likely to cause him to explain himself further, digging an even deeper hole.

Person 1: Man, he won’t stop Tysplaining
Person 2: I know! Last week he explain the circulatory system to a cardiologist. He got all of his facts wrong.

transplaining 

When a trans-person tries to explain your sexual identity or orientation to you contrary to the fact that this is a personal choice and everyone has the right to identify as they please.

Person A: I'm super-straight
Person B (trans): That's transphobic, genital preference isn't a sexual identity..
Person A: Please don't transplain to me, I know what I am and it's not for you to decide. Transplaining is superphobic.

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 )

Transplaining 

When a Transgender person or an ally tries explaining sexuality and science to Super Straight people and tries to invalidate their very real and valid identity in the process.

Trans: there's no such thing as a biological female read up on your science. And Super Straight can't be a sexuality it's a preference.

Super Straight: You're Transplaining. I don't know where you're going with this... But it's not in Super Straight pants.

Transplaining 

When a transgender person (generally who was previously male and has transitioned or is in the process of transitioning) continues to exhibit "mansplaining" behaviour, but not longer associates with that gender.

"OMG I was just showing them my makeup routine, and they started transplaining to me about why I shouldn't be using that foundation for my skin."
