i had one when i was 16, 6 years ago... i remember when i passed it!!! me and a bunch of my buddys were playen football at a school for fun, i was carrying a 3 gallon bottle of cranberry juice to help me piss.. my back was hurting all day, like someone was sticken a knife in mt back, well as the day went on i think i peed twice, the 1st one wasnt bad at all... at the end of the game i went to pee b4 we left on the side of the school, i hit the ground i think i passed out cuz i was by myself when i pist, when i leaned up everyone was around me wondering what happened... it came out worse thing thats ever happend to me so far!!!
