It's not very linguistically clear! But a lot of people use 'bi' to mean 'my own gender and other genders', which is one reason it works. And please don't apologise for not knowing—especially if you aren't in that area of queer community, it's not obvious! And you were clear about your lack of knowledge and asked for input in a way that made it clear you wanted to learn more, which is all we can ever hope for. (Can't help with the linguistic problem, but inventing words for queerness is always a problem of its own...)

I understand that it's possible to listen to Penumbra that way, but based on the last show like that I heard of—Thrilling Adventure Hour, I think?—I really enjoyed the premise of one show but couldn't deal with hopping through all of it to find just that. Perhaps at some point I will, but... unlikely right now! :)
