The fact that you used the phrase "Lazy ass" instead of hyphenating it is actually hilarious.
When it's non-hyphenated, you are using the word 'ass' as an adjective.
You just described them as butt people. DON'T CHANGE IT IT'S PERFECT EVERYWHERE.

oh wow... what can you respond to a review like this?
Sorry?
You're welcome?
... I don't know. Lazy-ass is something that I say all the time and I never thought of it that way. Huh. I think it's safe to say that often when I write, I don't pay attention to how you can't type everything down the way it would come out of your mouth, you know?
I guess I could call them butt people, although it has that tiny little homosexual ring to it. Butt people. Nevermind, I like that!
