it’s a replacement for boymoding

Boymoding is the act of presenting masculine, especially in the context of a transfeminine individual presenting masculine to avoid transphobic harassment.

and yes this post is about being trans, more specifically how 4chan is harmful for trans people.

It does look similar to the 4tran stuff but that’s most of the terminology I’ve seen leak from there so maybe other 4chan communities use similar language
