No, that's entirely fine. I was just making sure, because you said above that they know what you mean. There is no communication there, just an impression given.

And if you literally can not think of a single case where you would actually want to truly communicate and have a cisgendered person comprehend it, that's fine. But for me, there are times when I'd love to articulate things to people and have them have a clue what I'm talking about.

You can take advantage of impressions with a concrete definition being present, you know. It doesn't require having no definition at all to do that.
