The fear of cockroaches. Simple as that.
The word comes from the (Modern) Greek words "Katsarida" which means "Cockroach" and "Phobia" which means "Fear".
e.g. Girl: AAA! A COCKROACH!

Boy: lol people that have Katsaridaphobia have never seen the video of the guy burning the cockroach with the

fucken blowtorch

Girl: Do you even know what fear is?

Boy: -gets dad whipping flashbacks-
Get the Katsaridaphobia mug.
