This one's a legendary story in my spic country, passed on for generations.

>be 2004, first ever Anime Convention here
>pretty neat
>lots of cosplayers, lots of japanese snacks and candy and shit
>suddently, two random guys pose for pictures
>apparently they didn't know each other
>they're a brown Kenshin and brown Makoto Shishio
>they drew their katanas
>they're real, they both look pretty cool
>one pose has them crossing over their blades
>agry pose
>*kashing*
>they get caught up in the moment and start fake dueling
>doesn't seem too fake anymore
>a few seconds after, Shishio fuking slashes Kenshin's finger and apparently the inner part of his elbow
>they fucking continue?!

>they stop when there's a sizeable puddle of blood on the floor
And ever since then, any sort of katanas are completely banned in any Con around here.
A LOT of people know this story, since I'm not a weeaboo anymore, but my brother is and told me he heard this from someone else.
His face when I told him I was actually there when it started and when it finished.
FF to present day, I'm going to my first con and I wanna finally cosplay with the objective of picking up a cosplayer and maybe picking up another one, so my almost 30 wizard brother gets laid for his first time, lol. Wish me luck pals.
