Question: what does it mean when someone wants a drink neat?
Answer: For a drink made without ice or mixer, you'd order it “neat,” and it would be served to you in an Old Fashioned cocktail glass. So, you might say, “I'd like a bourbon, neat.” To order a martini “up” or “straight up,” means you'd like it chilled. A cocktail that is poured over ice is “on the rocks.”
