Definition: The common bartending term "on the rocks" is exactly what it sounds like: serving a drink over ice. Often the term is used when referring to a straight shot of liquor poured in a short glass filled with ice, ie. "I'll have a Scotch on the rocks." "On the Rocks" can also be used when describing the preferred way to serve a mixed drink such as a Screwdriver or Sea Breeze.
