Staunch Ballbag

An alcoholic drink which consists of a hot pint glass fresh out of the dishwasher (or run under the water of a sink at its hottest setting) filled to the brim with rack/well gin, and consumed as a shot.

"Our friend said he'd have a shot of anything - so we conspired with the bartender to fix him up with a Staunch Ballbag"

"Holy shit, Josh drank a whole Staunch Ballbag - he's going to die"
