when you do a poo that rips your arse apart because it is so bloody big and massive. it feels like your arse has been rapped. it has chunky bits in it the size of tennis balls. wait that is a tennis ball. gross. can often get to be 25 centimetres- around! it really hurts. be careful you will need a larger size toilet. NOTE: try not to do a poo ripper in your pants.
