Masculante (n.)

A man who calls out other men’s bad behaviour. (Masculine + Vigilante - new word suggestion)

.

I'm suggesting this portmanteau as a new word to add to your vocabulary (and hopefully one day, the dictionary). It seems obvious really, and we need more 'Masculantes' around doing a good thing! I see a lot of superhero men on social media doing exactly this, so I thought it fit to give them a hero like name.
