“half-assed”

So today, on much of the off times at work, I’ve been thinking of rather interesting expressions.

Actually, I lied. I thought of it right now.

Think about it. “Half-assed”? Really? What difference would it make if you had both of your buttocks in the situation? What, would I play the piano better with both of my buns mashing against the keyboard than one?

I’m not even going to get into “I don’t give a shit”. Really, would you give someone your feces if you did care?
