Jack Balling 

Vigorously yanking down on the scrotum with one hand while jerking off the cock with the other. Typically performed in synchronous harmony until a climactic finishing release.

My balls are really sore today. I watched porn all day in my dorm room and was jack balling myself.

Jack

Jacks are classy people. They almost always have smooth skin that the ladies looove, and likes to stay out of drama! But, when a Jack gets into drama, he always backs off. A Jack is astonishinly good with th le ladies and can get pretty much any girl. We also cannot forget about their hair! A true Jack has nice, flowy hair and styles it amazingly. Jacks eyes are the best quality of him, and they always pop out and say, "I am rare, dont forget me."

Girl 1: Omg! Jack just asked me out! What should I say?
Girl 1's concience: Of course say yes! Hes is so sexy and nice and he will treat you well!"

Jack Frosting

Cum that was expelled through masturbation, ie- "Jacking", and has not been cleaned up, allowing it to go shiny and slightly crisp, like cake frosting.

Typically found in teenagers bedrooms, although fully grown men that have wank addictions have been known to jack frost their carpet on a regular basis.

Danielle thought she had hit the jackpot with Steven. He was kind, considerate, and seemed to be very house proud. She relaxed happily on the sofa, thinking about how great her relationship was- until she noticed the Jack Frosting on one of the cushions.

1. Supposedly an animator who has done several works online. Has his own subdomain on www.fat-pie.com, where he shows all of his animations. Speculated to be a fake made by David Firth, owner of Fat-pie.com to make fun of newgrounds.com animators who are terrible, but think highly of their own work.

2. Somebody who is terrible at what they do, but thinks themselves as some sort of God.

1. Look at the Parondies of tha salant man by Jerry Jackson.

2. Dude, you are a Jerry Jackson with how bad you are at cooking! Stop thinking you're so great!
