<human>: Hi reddit! I am typing this off my phone so forgive me already.

The fuck up happened yesterday but it isnt 24 hours since it happened.. It was my NFLAT exam yesterday..I had just been informed of it yesterday before. Some genius decided to invite a 12th grader science student and put him in a commerce assessment .. basically a huge survey if you know what I mean..

I reached there 1 and a half hour before I planned to, everything goes well, I was the first to reach there ... our school's representative shows up with some other students whom I dont know, maybe 12 graders.. So they were chatting among themselves , and then there was me , trying to find a good group to eavesdrop to... I finally found on and they were talking about Naruto.. Eureka I think!

I move close to them, they were trying to remember the correct word that sasuke from Naruto calls his brother when he was young.. someone said nee-san and others began to argue about it that it wasnt nee-san.. Unfortunately for me, I remembered it as nee-chan ...

My FU: Out of nowhere, from the depths of my introverted mind, the sudden urge to correct them was very high...As I try to stop myself , battling my subconscious, I blurt it out while trying to say it in a low tone but my subconscious makes into a higher decibel value..precisely hitting the awkward point between sheer loudness and pin drop silence.... They all look at me like * insert girls with red cups at party staring at you like dafuq meme * 

This spread like wildfire in my school today as I have become the nee-chan guy...

Can you summarize the given text in a few sentences?
