the act of showing off your 'well exercised right arm' in a battle of an arm wrestle, usually ending up with the 'Jason' as a winner. unless the 'Jason' loses, he/she becomes saltier than the sea.

*arm wrestle finishes (the 'Jason' wins)*
guy 3: see... Jasonism

The abiltiy to predict percentages of occurring things, sometimes magically from thin air, and have them become fact. Also, facts and sayings are backed up "unnamed" freinds who can either be reached by phone but are never actually dialed, or who have first hand knowledge. The first hand knowledge people have names that no one in the group receivcing the Jasonism has ever heard of.

Also followers of Jasonism hoarde cell phones in packs.

The belief in Magic as defined by millions of High School intellectuals.

Jason: "Magic."

Jason is a sarcastic person, but when you get to know him he will talk and joke around with you. He is a hopeless romantic that dreads being alone. He calls the woman that he loves beautiful not hot. He makes sure the lucky girl he has in his life is ok at all times. He tries to be a good guy to everyone and is always trying to clear his past.
