Millie Syndrome

Millie is a character that is married to another character named Moxxie
Both characters are from an adult animated web series called Helluva Boss that was created by VivziePop, which can be found on YouTube
Millie is commonly known as just "Moxxie's wife"
Many people's reasoning for this is that from their perspective, they do not see much of how she is outside of Moxxie, and most of the things she does revolve around Moxxie
So, when someone uses the term "Millie Syndrome", what they mean is that the character is severely underdeveloped and their existence seems to revolve around another character as a whole

"This character is suffering from severe Millie syndrome"

Morris-Davies Syndrome

A condition where a medical doctor experiences rectal prolapse that worsens eventually leading to their anus enveloping their whole body. This is particularly prevalent in Shanghai, China.

"You have back pain? I don't care, I'm going to nullify all of your refills for your pain medicine because I can." The doctor then turns into one gigantic anus and is inflicted with Morris-Davies Syndrome. No known treatment is available.

Reco syndrome

A condition in which you forget faces within a very short amount of time. I forget what people look like a lot, I have to be really close to people in order to recognize them, unless I’ve known them for my whole life.

Reco syndrome: Bob was looking for his friend, he couldn’t find him anywhere, his friend walked towards him and then bob could recognize him, even though his friend was right in front of him the whole time just further away.
