A method of masturbation that is similar to "jacking off" but the masturbator stops beating his meat when he reaches optimum hardness (about 15-20 ohms or 3-5 minutes, depending on stamina level) instead of ejaculating all over himself and/or the area of seminal wreckage. This is usually performed immediately prior to sexual activity. May encourage an amateur robber to steal (jack) valuable things from other people.
Hoe: "Man is that all you got? You really need to go somewhere so you can jack on and hit dis shit right!" Jack: "No prob, just give me a handjob before i have to bust out da Playboy magazine again..." Hoe: "You know my hands can't fit dat little ass worm you call a dick, go to the bathroom!" Jack: "Alright, I'll be back." (Goes to the bathroom and jacks on, and comes out wearing a superman suit with dick hanging out) Jack: "Have No Fear, SUPERMAN is here!" (Dives straight into the pussy) Hoe: "That was so much deeper... Where's my money?" (Jack gives her $350) Hoe: "Wow, i thought you didn't had it in you... You're my hero!" Jack: "As long as my Jack is on, anything is possible!" Hoe: "Whatever." ((Meanwhile, in the streets)) Nigga: "Yo homeboy, u down for hittin deez licks wit me n my goons?" Homeboy: "Hell yea, as soon as i het a chance to jack on first."

Person who is kind & wholesome until pushed over the line. Reference to baby JackJack from "The Incredibles" Movie.
Don't keep pushing him. He's going to go Jack-Jack.
Be careful with him. He's got a Jack-Jack personality

When a guy is jacking off and is interrupted by a second individual who "lends a hand" and finishes the job.Ideally,the interloper could be the wife,girlfriend,a hot maid,or cute neighbor girl. Strangely,the good samaritan could be a sister,grandma,brother or roommate.
