Muscle Jerkitis 

When your dominant arm is more buff than your non dominant due to the effect of oftenly masturbating.

Man: "I swear, my left arm is strong, but it doesn't look like it compared to my right."
Man 2: "How often do you beat the meat? Sounds like a case of Muscle Jerkitis."

jerseyitis 

Mental disorder resulting from living in New Jersey for way too long; characterized by a strongly depressed demeanor, negative disposition about everything, and a general malaise of pessimism about future events.

A downhill spiral attitude in which one believes one is living in dystopia - prompted by the fact that one lives in New Jersey, where nobody smiles.

Joey: "This concert probably won't be that good. I doubt it will be worth it"
Jimmy: "Dude, what do you have Jerseyitis, this concert at PNC Bank Art Center's gonna rock."
