The Undertale Effect 

The Undertale Effect is a cycle that any form of entertainment media community can fall into.
Essentially, the community will COMPLETELY over rate the show/game/book/movie/etc., and defend it as if it is their life. The community will almost always turn the lovable, funny characters into cringe, and rapidly spread throughout the internet.
The strange thing is that the only outlets to suffer from The Undertale Effect are those from something that by itself is great. The show/video game/movie/etc. is usually great, and has many redeeming qualities but it is overshadowed by the atrocious and toxic fanbase.
Quite obviously, this is based off of the worst case of this ever happening yet - Undertale. I won't get into it now, but the smallest peek into the (dead now) community will tell you.
This has infamously happened to: Steven Universe, Five Nights at Freddy's, Minecraft, and unfortunately even Rick and Morty.
Right now, Rick and Morty has fallen into the Undertale Effect. Just look at Musical.ly, the fan art, the cancerous reddit copypasta, etc.

A term used when a video game or television show becomes unbearable to play/watch because of its fanbase.
"It sucks how badly the Undertale Effect ruined Rick and Morty."

The Undertale effect 

Once something popular releases, the community and any content made about it WILL degrade and become worse overtime.
"hey have you noticed the twitter community on welcome home keeps getting worse?"
"That, my good friend is the undertale effect happening in practice"

Foot prisons 

Socks. Annoying, sweat-causing, non-barefoot enducing, everyday socks.
The first thing I do when I take off my shoes, is rip off the foot prisons I had to wear inside them. That's why I prefer flip flops, even in winter!

cornholio 

Ruler of Lake Titicaca. Rumored to have a bunghole that gets very angry if it does not receive toilet paper. Cornholio the Great is often seen walking around with his shirt over his head and his hands in the air, chanting songs about his power, and his bunghole.
"I am Cornholio! You do not want to face the wrath of my bunghole, for I need TP!"
Butthead: Shut up, Beavis! (uh huh huh huh)
Beavis: Um, okay. (heh heh heh heh).

mickey mousing

In a movie, when the music is syncronized perfectly with the action, just like a mickey mouse cartoon.
