It does confuse me, as a term. Pretty much every bit of meat that I eat was harvested and processed by myself or my neighbor. Given that we are going to be the folks eating it, it's pretty clean.
I clean my fish, deer, moose, beef critter, fowl, etc... I clean them very well. (They are delicious.)

You do understand that you are the very definition of an outlier, right?
So it would OK if the term only confused you, since you are supposed to be confused, given that you do these things differently than 99.99% of the population.
But I think the term is confusing in general, not just to people who "kill and clean their own meat".
That's certainly true, but I suspect I'd have been just as confused even before I moved here. Today, I know my meat is pretty clean. Back then, I'd have assumed it was clean because it hadn't made me sick.
