An urban legend is like 'A woman pulls up at a gas station and the gas guy asks her to come in the store to pay, so she goes in and well the gas guy is creepy and grabs her trying to say something but he stutters so she freaks and runs away gets back in the car and drives off, only for a masked figure to emerge from her backseat and kill her, the gas guy bwas trying to warn her about the killer' this is an urban legend, sadly i fail to find 'toilet shapes determine the swirl' in my book or urban legends!!!
