have heard none of these conditions, but they all have to do with
laughter. Gelotophobia is a fear of being laughed at, a type
of social phobia that makes them feel awkward. Gelotophilia is the joy
of being laughed at. Katagelasticism is the joy of laughing at
others. None are particularly good to have. Luckily these are not
common, so have a good laugh and enjoy yourself.
