What is a kashisty?

Answer 1

Oh, dude, a kashisty is like... not a real thing. It's probably a made-up word or a typo. Maybe someone was trying to spell something else and their fingers slipped on the keyboard. But hey, if you want to start a trend and make "kashisty" a thing, go for it!

Answer 2

A fictional hallucination of a character from an episode of Law and Order: Special Victims Unit. The episode is called "Coerced" and is episode 6 of the 5th season. Also it seems they spelled it kashisti in the script. The character believed they were a group of secret police out to get him.
