Undertale effect

A phenomenon in which a video game, movie, or other piece of media that was never intended to be perfect gets hyped up as such by its fan community, causing those diving in to have far too lofty expectations. This is followed first by disappointment when it fails to be perfect, then by backlash against the fans who hyped it up - and, inevitably, the game itself. This results in a cycle where the "fans" and "haters" become distinct groups who get increasingly vocal and vicious with each other, debates over its contents become less rational and more personal, until eventually all legitimate discussion about the original subject becomes impossible.

Popularized by the 2015 video game Undertale, as of this writing it is still extremely difficult to bring up the game in any context without getting attacked - either by diehard fans who refuse to recognize that the game has flaws, or diehard haters who refuse to recognize that the game has strengths.
I once brought up Undertale in a conversation. I got told to kill myself, and then the conversation veered off-course into bickering between the fans and the haters. That's the Undertale effect for you.

Undertale Fandom Syndrome

Undertale Fandom Syndrome(UFS), is a horrible disease that is founded in major fandoms. First discovered in 2014, it was created in its first stage with the FNAF fandom. It horribly spread when undertale became popular. Common symptoms include: comic dubs, weird fetish art, and annoying obnoxious children/preteens. Unfortunately, UFS has became a parasite that is sent to feed off hosts and cannot be treated or cured. The following fandoms that suffered the same fate include but not excluded: FNAF, Undertale, Cuphead, Bendy and the Ink Machine, Hazbin Hotel, and recently, Friday Night Funkin'.
Person: yo dude have you seen this game called Friday Night Funkin'?
Another person: yeah man that shit is really great!
Person: yeah it is, unfortunately the FNF fandom is making Pico x BF yaoi.
Another person: shit! Another game fell into Undertale Fandom Syndrome

Undertale Fans

*Sighs*
Let’s talk about the most scary, disgusting, disturbing thing I’ve seen since Obama.

Undertale Fans.

Not just the people that like the game, I mean the fucking bitches that ship soriel, make Sans x Reader lemons, and post nude pictures of a skeleton on the internet.

If you are one of these people, please, don’t be afraid to ask a responsible adult for help.

These types of Undertale Fans are disgusting narcissistic people who fight over a fictional skeleton.

Who the fuck writes the lemons?

Okay, I get it, Sans can have a magical glowing dick because he can preform magic and he’s a fucking skeleton that can talk, I get it.

But, who the fuck would want to be fucked by a 2D Monster?

Seriously, why?

People, get a hold of yourselves!

If you want examples, look at Underlust Undertail or Sans x reader lemons!!

People, get some help already!! This is fucking bullshit!

Every game gets ruined by fan girling bitches and lewd people!

I can’t enjoy pictures of Undertale without thinking of some stupid ass ship!

Jeez people, seriously, get. Some. HELP!!
