Etymology : Jack off probably received the definition to masturbate from the noun jack in the sense of penis or from the verb jack in the sense of raising/hoisting.
Source : After getting out of class, my friend told me he was going to “jack off until dinnertime and then start doing homework.” (Fall 2011)
