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 commences*
guy 1: why is Jason doing an arm wrestle again?
guy 2: dunno ask him
guy 3: don't bother, it's...Jasonism
*arm wrestle finishes (the 'Jason' wins)*
guy 3: see... Jasonism
