A krishma is the calm, funny alternative to a Sushma. Also known as a Sushima, Sushma is often aggressive, cannot be trusted and will retaliate when provoked. Krishmas will make you laugh, sushmas will inflict pain
Person 1: Oh, hi Krishma
Sushma: GGGRrrrrrrrrrrr
Person 1: AAAAahhhhh, run for your life!!! It's a Sushma!!!
