It's supposed to mean stuff like not asking for help when you need it, or being overly aggressive in social situations so you don't appear weak. FWIW I hate the term because it's become a catch-all for "things men do that I personally don't like".

Not asking for help sounds like stubbornness and inability to admit a failure or lack of knowledge.That's more a cultural thing from my experience. Common in Asian cultures but also prevelant in older western generations.

Being overly aggressive sounds like a character flaw, psychological problem or poor social conditioning.

I guess if you really want you can label them masculinity and then you'd be right but personally I struggle to draw the connection and find the idea of tying the word toxic to a gender dangerous. Nothing wrong with being masculine. Nothing wrong with being feminine. Nothing wrong with being overly either whichever your gender.

People who want to label me toxic for having a penis is going to struggle working with me, and it isn't my masculinity that's the problem.
