A person with below 0 iq, which is impossible in itself, but somehow the children below 9 who play him achieve it. Yasuo is the only kid friendly champion in league without any NSFW+ ties online because only children play him. He is the most cancerous champion in existence, second only to Teemo, the devil himself.
Derived from the game League Of legends a Yasuo main has accomplished nothing and will never do anything in his life, they are usually stuck in this bubble where they think are awesome because they play someone who takes no skill.
A dude that mainly plays the League of Legends character "Yasuo'' that is completly over powered and broken.
Making them an complete asshole
''Hey dude do you play LoL?'' ''Yeah i am an Yasuo main ''
"fuck you''
