floppersaurus 

A floppersaurus is a huge penis which has to pertrude over 15 inches. The name derives from the comparison to a dinosaur in size and is possesed by very few. If you have a floppersaurus then you're sure to score one, or two. However the floppersaurus can have a down side as 15 inces can be enought to perferate a womb so be careful.
