A girl who, although normally repulsively unattractive, skanky, or a completebutterface, is transformed by a night of hard drinking to become a 'knockout' gorgeous beauty by the time that 'last round' is called at the bar.

"Jesus Christ! What they hell is Jimbo doing with that turbo skank!?"
"He does this every Friday man, she's his last round knockout"
