Overview
Scary Buns (まんじゅうこわい, Manjyuu Kowai) is a rakugo story, or to be specific, a comic story.
History
Manjyuu Kowai was first heard in year 1776 (5th year of Anei era), published as one of the rakugo stanzas along with Jyugemu and Meguro no Sanma.
It was played in many stage dramas, mainly as a comic story.
Plot
The comic story starts with a gathering of a few youngsters who are free, and each of them started talking about thing they feared most : Snakes, spiders, or even ants. One of the youngsters laughed at them, calling them pathetic for fearing such trivial stuff. The others then proceed to counter that certain guy by stating "No such thing as fearing nothing!", followed by forcing the guy to spit out one of his fears. He then followed by "actually I have one", which is buns.
He then stated his reason "Just talking about bun makes me feel bad", and leaves the room to sleep at the other room just beside the current one.
The offended youngsters then decided to teach him a lesson, and gathered some money to buy a pack of buns to scare him. To do so, they bought the buns, and put it around his bed while sleeping. To prevent him from escaping, they locked the door as well.
Soon, a scream was heard and the youngsters went to check it out, only to find out that the man ate off all the buns.
"Ahhh, so scary, so scary that I had to eat them all!", "Too delicious it's scary!"
The result ended up making the group of youngsters even more angry, and asked "Then what is the thing you feared most!!?".
This time, he answered "Well at this area, rich tea is by far the scariest", and the story ends.
Usage
This tag is mainly used for artworks that are supposed to look scary but can't help but to "taste it". With the saying "One wrong step and you'll be on the road to death, but it's not about being so scary that you'll be scared to death, but you'll die of diabetes..."
In other words, artworks that are so stimulating that in return it became something scary (which is actually not) can be attached using this tag. It is also used as a parody to the comic story, but such cases are almost rare to none.
It's similar to "HNNNNGGG" in the western fandom.
