Memes of Production

If you could unilaterally embed something into the cultural consciousness as being distinctively transmasc culture (similar on scale and arbitrariness as cat ears and programming socks), what would you pick?

I found your comparison to bisexuality interesting, given that some of the things that I've seen posited as being bi culture are super arbitrary in a way that makes it abundantly clear that the only true motif of bi culture is desperately trying to claim whatever we can as bi culture, to give ourselves a sense of relevance and being seen (aside from dual wielding daggers, that is. That's obviously bi culture)
