Bottle-killer cocktail

A cocktail made with at least one ingredient that was the final shot or other amount in its bottle. A variation on a "bartender's choice" type cocktail order, one that allows the bartender some freedom while under one key creative constraint. Obviously, not a recommended order if wait staff are slammed and / you can't actually have at least a small conversation with your bartender.

I had to explain to the waitress Tracey that a bottle-killer cocktail is any cocktail that kills (finishes off) at least one bottle in its creation.
