a smelly, empty sack that’s been sitting in the back of a closet for years and nobody wants to touch it.

My brother found the hacked sack in the garage and tripped on it.

The teacher left a hacked sack in the classroom and it stank like a dead rat.

I stepped on a hacked sack and it felt like stepping on a pile of rotten eggs.
