A game developed from being very bored... Involves throwing random objects at each other (pillows, balls, bottle caps, etc.) shouting hadouken everytime a projectile is launched...
Person 1: Dude, There's no one at the skate park, and I don't feel like skating... I'm bored as fuck!
Person2: Ok, I know how to settle this... Hadouken war!
Person1: Wtf is a hadou...
Person2: *picks up random cigarette box and throw it* HADOUKEN!!!!!!!!
