A customer asked me the origin the the word "cocktail". I didn't know but promised to look it up. This is part of the origin of the word "cocktail" from wikipedia-

The earliest definition of "cocktail" was in the May 13, 1806, edition of the Balance and Columbian Repository, a publication in Hudson, New York, in which an answer was provided to the question, "What is a cocktail?". It stated that:

Cocktail is a stimulating liquor composed of spirits of any kind, sugar, water, and bitters — it is vulgarly called a bittered sling and is supposed to be an excellent electioneering potion, inasmuch as it renders the heart stout and bold, at the same time that it fuddles the head. It is said, also to be of great use to a Democratic candidate: because a person, having swallowed a glass of it, is ready to swallow anything else.

Is this like "koolaid"
