Get the bottle bum mug.
A miniature bottle of alcohol, often referred to as an "airplane bottle", which contains 50ml, or about 1.7 oz of liquor.

A fave of street bums who panhandle for a couple of bucks and stumble into liquor stores for a "bottle".

People sneak these into events to slam instead of buying shots.
