desjardins is a FtM transsexual that has recently started using testosterone and has masculinization surgery planned. He's saying he wants to wear one of those shirts as a celebration of a major milestone achieved: removal of female breast tissue and so the elimination of one more female trait.
Nora responds with (words to the effect of), "Oh yeah i know exactly what you mean, I wear those on-top of my huge tits which I sling into a sports bra. So masculine, I'm totally on your page." Nora's "masc"/"andro" days are her doing her "mean man face". She's so insensitive she's equating her doing her "mean man face" with a FtM transsexual getting his tits surgically removed.
FFS Nora, men don't have huge fucking tits and that is why
desjardins is saying he wants to wear one of those shirts, he's wants to say to the world, "Look I have a chest like a man!".
desjardins is also weight training to try and achieve a male-typical chest. But Nora knows just what that is like because she puts on a man's shirt and does a "mean man face".
Nora, you crazy bitch, you know nothing about what it's like to be a man. There is
nothing masculine about you--you have huge tits, huge child-bearing hips and you menstruate. You are a baby factory--the polar opposite of a man. Please stop pretending you have some insight into masculinity. You are a wretched person sticking your fat ass where it doesn't belong.
When you start injecting yourself with testosterone esters, have your huge tits surgically removed and have the fat suctioned out of your huge hips then you can start speaking about masculinity. Until then stay in your fucking lane. And if you want to get some insight into masculinity listen when natal men and FtM transsexuals speak rather than interject your ridiculous ideas about masculinity.
