a fifth
A fifth is 750 ml of pure liquid hell. It’s not a pint, which some clueless people think it is. A fifth is the size of your regret after you drink it.
I thought I was getting a pint. It was a fifth. I’m still mad.
My friend bought a fifth. He drank it. Now he’s in the hospital.
I tried to sip a fifth like it was a fancy drink. It was just a fifth.
