Soda jerk (orsoda jerker)^[1] is an American term used to refer to a person—typically a young man—who would operate thesoda fountain in a restaurant, preparing and servingsoda drinks andice cream sodas.^[2] The drinks were made by mixingflavored syrup,carbonated water, and occasionallymalt powder over either ice or a few scoops ofice cream. The drink would then be served in a tall glass with a long-handled spoon, most commonly known as a "soda spoon", anddrinking straws.

Soda jerks were relatively common in the United States from the 1920s until the late 1950s; due to economic and social trends, the occupation essentially no longer exists.

The termsoda jerk was a pun onsoda clerk, the formal job title of the drugstore assistants who operated soda fountains. It was inspired by the "jerking" action the server would implement to drive the fountain handle back and forth when adding soda.^[3] The soda fountainspigot itself was typically a sturdy, shiny fixture attached at the end of a pipe which protruded over the counter and curved down at the end for filling glasses. Since most drinks required carbonated water, the tap handle was built large to accommodate frequent use of the fountain.

The practice of operating a soda fountain in adrugstore reached its peak popularity in the 1940s^[4] but was popular from the 1920s through the 1950s. The position was coveted, and was commonly only awarded after protracted menial labor in the store.^[4] Soda jerking was dominated by popular young men with loud personalities and good people skills because of the popular environment and "cool" association. These boys who worked at the shops were expected to serve the drinks and also socialize and entertain the guests.

Michael Karl Witzel describes anarchetypal soda jerk as "[a] consummate showman, innovator and freelance linguist ... the pop culture star of theGilded Age".^[4]

The proliferation ofice cream parlors declined asdrive-ins and walk-upfast food stands grew in popularity, and grill andfry cooks replaced soda jerks.^[4]

Soda jerks were known for having their own lingo for how their drinks were made. They created nicknames for different drinks. For example, they called a glass ofmilk "baby" and a strawberrymilkshake "in the hay".^[5] ACoca-Cola with ice was called "scratch one". They also had lingo to express how they wanted their drink to be served.Coffee, or "draw one" would be served strong if called "draw one from the south". If a drink was ordered with extra ice it was "heavy on the hail".^[5]

Some of these terms are still used today.Egg creams, the shorthand for a chocolate soda with some milk, are served in many places and are especially known inNew York where they originated.^[6]

Another term from soda-jerk lingo that remains in use is "concrete", a name for an extremely thick milkshake or custard. For example,Culver's continues to serve their famous Concrete Mixers.^[7]
