Pentheraphobia is an intense fear of Mother-in-Laws.
It’s the fear of things that (theoretically) pose no
actual danger. It’s kin to the fear of computer cookies,
singing karaoke, being medicated, or being
microchipped (labeled) by strangers or family.
Isn’t there also a phobia for waking up in strange places?

“There are various forms of the disease in which the victim
is unable to say “No.” Some of these forms are more serious
than others, and often lead to electrocution or marriage.”
