Coney Island Chicken (hot dog)

"Coney Island chicken" has been a slang term for a "hot dog" since at least 1920.

Hot Dog Is Having Its Day:

In the variety of local names applied to the same product a national term often proves useful. The trade has already learned to respond to the names, "Coney Island chicken," "shore dinner," "half smokes," "weinies" and so on. To one manufacturer came an order for reed birds. He replied that he was not in the poultry business. "Send hot-dogs," the customer wrote back; and the manufacturer understood.

When the first half of the 2nd game was dull I got a laugh out of a flip-crackling hot-dog vendor, who kept yelling: "Here ya are! Get ya hot franks -- better known as Coney Island chicken!"
