We're getting completely off track here but I agree; to me it seems to be kind of an extension to grammar pedantism, as it only serves to indicate little beyond "I know this word's origins". What's wrong with "viruses" or "octopuses"?
And if we don't stop to smell the roses, how will we remember how good roses smell?
So let's not defenestrate curiosity wherever it leads with the culture of "no," because you're not a moderator. So don't pretend to be the king who decides what is permitted and forbidden to be discussed; that's contrary to an open and free society.
There's nothing wrong with "viruses" or "octopuses." Please read and understand that "faux Latin" means these tweaked "smarty" words aren't even Latin half of the time.
I had actual Latin on a license plate frame on a sports car that roughly translated to "eat my dust/shit/detritus." I can't remember the exact tenses of the words, but it took me a while to get it right.
