As far as internet photo trends go, this one is certainly more fun than planking, Eastwooding or milking (don’t Google that one at work). Hadoken-ing, for lack of a better name, is a trend gaining popularity among Japanese students. Basically one person reenacts the “hadoken” attack from ‘Street Fighter,’ and everybody else plays along by jumping in the air. Some folks think it’s actually an homage to kamahameha from ‘Dragon Ball Z.’ Whatever it’s referencing, it is about a zillion times more entertaining than teenagers dumping a gallon of milk on their heads. Take a look for yourself.
