manniversary 

The anniversary of a transgender man's transition beginning. Often marking his first testosterone shot, when he began binding/dressing in male clothes, or whatever he decides 'began' his transition.

Have you seen the FTM 1 year manniversary videos on youtube?

It's amazing how much muscle and hair growth he has-it's only his first manniversary!
