Small food items you would not normally eat, unless presented to you as the only food option at an event where you drank a bit too much already, and plan to continue to drink.
Appetizers that you typically get in a chain or fast food restaurant that are usually high-fat, high-cholesterol, and high-calorie (but we usually eat them anyhow).
Let's just order some crappetizers: chili-cheese fries with ranch dressing, loaded nachos with extra cheese, and some potato skins with bacon and sour cream!
I cannot believe that server coerced us into buying twenty dollars of trappetizers last night: fried zucchini, raw Buffalo wings, onion rings, fries, and pumpkin slices.
