hot dog

A hot dog is a cooked sausage, typically pork or beef, served in a sliced bun with condiments like mustard, ketchup, or relish.

It's a staple of American baseball games, street vendors, and backyard cookouts.

As an exclamation, hot dog! expresses enthusiasm or delight—old-fashioned but still heard.

To hot dog is to show off with flashy maneuvers, especially in skiing or surfing: He was hot-dogging down the slope.
