i could eat the north end of a skunk moving south
A way of saying you're so hungry you'd eat a skunk's butt if it was moving and smelly.
I could eat the north end of a skunk moving south after walking 10 miles in the snow.
My stomach is growling like a lion. I could eat the north end of a skunk moving south.
If I don't get food soon, I'll start eating skunks.
