Big old booty. Term used by statistics geeks and hedge fund weenies. From the Greek word kurtos, meaning bulging, kurtosis is a measure of how "tight" a probabilitydistribution of a random variable is around the mean. A positive kurtosis value indicates that many values fall far away from the mean, which are called "fat tails" when shown graphically.
