A twenty dollar bill. And twenty Franklins would be two thousand dollars, not twenty. I think T Wade was going for twenty Washingtons. Let's not confuse the foreigners, now.
I'll trade you my five boring Jacksons for that sweet ass Franklin.

(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!!!

Clark: GODDAMMIT!
