Wetback comes from Mexicans (primarily) illegally entering the US by swimming across the Rio Grande River. Dryback is any illegal that did not get wet while illegally entering. Cuban refugees - if they can step onto dry land (Dryfoot) before being seized, they qualify for political asylum, if not (Wetfoot) they can be deported. Some if not all of these terms can be considered derrogatory in nature.

Wet back and dry back are terms used to describe the design of a boiler's combustion chamber. In wet back boilers, the combustion chamber is surrounded by water, which helps in heat transfer and increases the boiler's efficiency. In dry back boilers, the combustion chamber is not surrounded by water, resulting in a slower heat transfer and lower efficiency. The terms refer to the location of the water and its effect on the boiler operation.
