Grab one of these, and turn it on yourself. Grab some sake, which is a Japanese rice wine made by fermenting rice that has been polished to remove the bran. Grab a katana and start up your match. Once in game you will unsheath your katana, and lay it in traditional style along your keyboard.

I'm going to stop this.. Like. I can't continue it.

I would suggest watching Trinimmortal's "The only Yasuo guide you will ever need" YouTube video. Sorry that I can't link it since I'm on my phone.
