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!"
