A large testicular cyst, often becoming so huge that it begins to split and grow inside-out. Cause of these cysts are unknown but men who are sexually active have a .3% higher chance of getting one. The only known cure to a Jackson is by inserting a super-heated rod into the center of the cyst (also called the Lincrem) which will erupt the cyst, clearing it of excess pus and fluids (The fluids are too thick to be taken out via syringe), finally the excess fold of skin must be quickly surgically removed to prevent a bleedout.
That man's Jackson has become infected, it must be operated on immediately.

(Verb) to Jackson, Jacksoning, Jacksoned. The act of Jacksoning someone is to somehow, exploit or otherwise manipulate, a completely unwilling party, to provide an aid or a service, while providing absolutely no short or long-term compensation. It is executed to such a degree of dexterity and skill, that often, the Jacksoned party does not fully comprehend that they were infact Jacksoned. One can often comment on the laziness of a Jackson, or on how much a Jackson is in their debt, or can discuss previous incidents with other victims, and yet will still unwittingly get Jacksoned by that same party. A Jackson will always leave an opening available for any future goods or services they may require. Jacksoning is not limited to any one-on-one manipulation but can extend to several individuals, for several different things.

Side note: Jacksoning is not a spontaneous act, that can be achieved by anyone. It is a delicate art that has to be practiced often, and planned to perfection. A good Jackson can achieve almost anything for the price of nothing.
Steven: hey buddy! where you going?

Clark: I’m just gonna go buy a pack of cigarettes.

7 hrs later.

Clark: (to his friend john) man, earlier I was walking to my car, to buy a pack of cigarettes, and I ran into Steven. Somehow we ended up at dinner, I paid for his meal, then dropped him off at his house, where we ran into his landlord. He somehow convinced me pay for his next 2 months rent.

John: That’s odd!

Clark: yea, I know. He also took my pack of cigarettes. I’d go buy another pack but he borrowed my car for the next week. I had to walk back, cause I didn’t have anymore money to pay for a cab.

John: DUDE! You just got totally Jacksoned!!!
