A reciprocating (often involuntary) motion of a hand around a peanus resulting in a spluttering of a gooey substance from the orifice of the above mentioned peanus. Often, the peanus belongs to the hand but not always. If unobstructed, the travelled distance of the substance varies directly as the pleasure the owner of the peanus will experience.
Yesterday I jacked off (regular verb!) on a girl sleeping next to me in the train and I polluted her forearm with my sperm! I was very proud of myself!

It helps to think about kinky sex trysts with five-year-old boys when jacking off. You will cum quicker.

A person who prevents everyone around them from discussing the finale of "Lost" because they haven't watched it yet. The prefix "Jack" comes from the first name of the candidate Jack Shephard. The suffix "off" refers to the person being a jerk-off.
Co-worker 1: Holy cow! Did you see "Lost" last night!
Co-worker 2: Shhhhh! This Jack-off dvr'd it last night and watched the ball game instead. We'll have to talk about it tomorrow.
Co-worker 1: What a jerk-off!
Co-worker 2: You mean Jack-off.
Co-worker 1: Yeah, whatever.
