This is a term used to describe a man who has a fragile sense of masculinity for whatever reason. It can be used for someone who tries too hard to fit the male stereotypes in fear of looking too feminine in front of society.
Jim: I wouldn't dare wear tight jeans, im scared that someone might think im gay.
Jordan: Dude, stop having such fragile masculinity and get over it. It doesnt matter how tight your jeans are, all that matters is how comfortable you are in them. Stop giving a shit about how 'manly' people think you are. Define 'manliness' through what you do, not through society's mindset.
A cultural movement in which men use over-the-top fashion to express themselves. Through makeup, jewelry, and boob-windows, they enhance their masculinity.
Somebody who advocates for menās rights. (The rest of the definitions here are biased.) Someone who wants Men And Women to have equal rights in the courtroom, social, and other environments. For the rest of the biased definitions, we get it, your a lesbian misandrist, no need to rant about it on the internet.
