Irish Gutbuster

A shot glass with a pinch of chewing tobacco (usually copenhagen or red man brand) placed in the bottom, then filled with whiskey. Called a gutbuster because of the fact that it takes a strong stomach to be able to refrain from vomiting.

Johnny threw a shot of Irish Gutbuster back and immediately threw up all over the bar.

Italian Gutbuster

Shoving a Tommy gun into your anus and viciously thrusting is inside of you, but each time you make a sound, you fire a single round.

Oh Josh there? He's doing the Italian Gutbuster .
