Katagelasticists actively seek and establish situations in which they can laugh at others (at the expense of these people).
There is a broad variety of things that katagelasticists would do—starting from harmless pranks or word plays to truly embarrassing and even harmful, mean-spirited jokes.
[1][2] They would be of the opinion that mocking others is part of the daily life and if others do not like being laughed at, they should just fight back.
[1][2] This condition often makes it difficult for sufferers to gain and maintain acquaintances and romantic partners.
[1][2] The term was coined by Christian F. Hempelmann and Sean Harrigan[3] from katagelastēs (καταγελαστής), Ancient Greek for "mocker".
