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.
Typical Yasuo main.

Usually they are known for feeding, inting, throwing, (Usually leaves/disconnects from the game) and blaming their jungler for not ganking them even their jungler is a lane away.
