A shot of alcohol consisting of the combined remaining drops of various seemingly empty alcoholic bottles, containers and cans which include but are not limited to hard liquor, wine, beer, sake or even NyQuil.
We completely ran out of alcohol late last night but Bob needed his fix so bad he took all the empty bottles made a concoction shot with whatever drops were left. What a pathetic lush.
