The term jack off is a slang term that refers to penile masturbation. The term may stem from the use of the word "jack," a device used to lift heavy objects, often a car. A car is said to be "jacked up," when it is lifted and, much like male masturbation, doing so involves a repetitive, one-armed motion.
