Input: Text: this happened about a half an hour ago. so i walk into the common room in my dorm and some of the guys are playing ninja. ninja, if you know, is a game where you try to smack another person's hand before they can move it. so anyway the game was down to me and one of my good friends when it started getting heated. i made a quick move to his hand which was extended over his head and he was at my back, i miss and my hand keeps going and pulls my elbow behind it. i heard a crunch and he starts holding his nose and in a few seconds blood just starts flowing out of his nostrils. there was just so. much. blood. now his nose is broken and he is holding a bloody towel to his croocked nose.
tl; dr: got carried away playing ninja and became a ninja
