Is this Okay?

HIi,
So I wrote a supplement essay titled, “Pennachromania-The Love of Colored Pens” about my obsession of writing everything with colored pens.

I completely made up that word. Is it okay? At the end I said “Pennachromania is not a word found in the dictionary or any published texts, but I can be found with me.”

Is it clear enough that I made up the word because I don’t want admissions to think that I’m a complete idiot for thinking that its real.

Thanks.

I think its fine, and kind of fun.

I would reword the sentence you quoted, but the topic sounds interesting!
