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.

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."

Transplaining 

When a transgender person or transgender ally talks about their identity and/or general issues the transgender community face, and a transphobe wants to silence this discussion, they label whatever the transgender individual says as "transplaining".

Thus, "transplaining" is a slur a transphobe will use to label and stifle any conversation by a transgender individual or ally regarding trans issues.

Trans man (FTM): "I prefer he/him pronouns and prefer using the men's toilets, especially as I present as a male, thus using the women's toilets will cause confusion and makes me uncomfortable".

A transphobe/gender critical/terf: "You're transplaining!"

Tardsplaining 

Whenever someone who has no idea what they’re talking about tries to explain something. Instead of giving further information they just get loud and angry silencing their opposition. People who tardsplain once are likely to do it constantly and can often fool fellow tards into thinking they are smart.

David: That tony douche is a real tardsplainer, he tries tardsplaining everything, and just talks like a pompous fag.
Dylan: yeah, Tony’s fucked up, his shits all retarded and he talks like a fag.
