Hadorken
A person who's so obsessed with Street Fighter that they think they're in the game and would fight you for a combo.
He walked into a store yelling 'I'm coming for you, Sagat!' and got kicked out.
He tried to beat my mom at Street Fighter and she just laughed and said 'I've got a combo that will make you cry.'
He once missed a date because he was too busy practicing his Hadoken in the mirror.
