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 probability distribution 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.
Sir Mix-a-Lot would dig the slammin' kurtosis on that chick!

Do these pants make me look like I have excess kurtosis?
