The art of jacking on is a much unknown art lost long ago in the Roman empire
Archieologists have discovered several requirements for jacking on by studying scripts from roman murals
the requirements are as follows
1.Strong left leg
2.Slightly short middle fingers
3.a high pain thershold
4.6 foot 2.5
we would ask anyone with these qualitys to ontact their local museum and ask about the phenomenon and then ask were they can go for testing into these qualitys in relationship to curent reasearch
"Oh man last night i had the biggest jack on last night and I nearly broke my left leg as it wasnt strong enough"
"That totally sucks!"

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."
