look up any word, like pussy:
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.
Let's go get some bum bottles for the concert. I'm not payin $10 a drink!
