A derivation of the words jack off used for over 50 yrs in Pittsburgh. I used it as a kid even before I knew what jacking off was. Used it this manner because it seemed less offensive to the ear. It was especially used by people south of the Monongahela river. My Pittsburgh accent is so strong that a woman walk up to me in a gym in Phoenix and said"Your from Pittsburgh aren't you" by overhearing a conversation. Still in use by older Pittsburghers but dying out.

A Pittsburgh insult. Basically a 'jack-off'. But if you call some one in Pittsburgh PA a jagg-off, it is basically like saying 'FUCK YOU'
