Damn if you're not right. I stand corrected. I wonder why I thought I needed to mentally camel-case it? Is that what it was? Was it ever capitalized this way or have I been making it up this whole time?

I think it's Mandela Effect. I don't know of any other words that can have the letters 'Xc' in sequence in a capitalized word, so my brain must just reject the idea even though I've literally seen it over and over right in front of my eyes.
