You won't learn this by participating in online queer discourse, but coining new terminology actually isn't the goal of serious theoretical analysis. It's more like something you should treat as a last resort for when you've put in the work to confirm there are no better options to convey the ideas you've arrived at.
I dunno, I think there's some merit in a good contraction. Like you could say "The specific combination of transphobia and misogyny typically experienced by trans women" but that's a mouth full, especially for a topic you might up discussing a lot because transmisogyny is rampant.
All this to say, while you might have perfectly good terminology to begin with, if you need to discuss something a lot you may wish to shorten it because it would be exhausting to say its formal name each and every time.
So Julia Serano's Whipping Girl, one of the foundational texts in transfeminist theory, is one of the contexts where coining new terminology is in fact justifiable. On account of presenting the foundations of a whole-ass theoretical framework.
This post is for when Tumblr users want to coin some shit like "transmisandriblanc" because they feel left out from having their own word.
