Cuke-a-Cola

"Can that Coke, keep cool with a cucumber Pepsi

slake our thirst than with a cold carbonated beverage. And if you're
in Japan, now you can keep cool with a cucumber-flavored soda."

Old-timey Slang of the Day

sizz-water: carbonated water

My old dictionary has a great sentence to illustrate this, from a 1905 book by one Hugh McHugh called You Can Search Me: "The waiter had crowded the sizz-water into the wood alcohol."

Whuh? You can search me.
