Investopedia explains 'Platykurtosis '
The opposite of platykurtosis is leptokurtosis, which describes a distrbution that is more peaked than a normal distribution. Also, a platykurtic distrbution has thinner tails while a leptokurtic distribution has fatter tails. Fatter tails equates to more data points at the two ends of the distribution, while a thin tail indicates there are more data points centred around the mean.
