Yasuo is one of the many characters of League of Legends, and one of the things that are considered trash by the Deprimus group. Yasuo is an agile swordsman, trained to wield the air itself against his enemies. As a young man, pride led him down a path of loss, costing him his position, his mentor, and ultimately his own brother. Disgraced by false accusations and now hunted as little more than a criminal, Yasuo wanders his homeland seeking redemption for his past, with only the wind to guide his blade.
In-game, Yasuo is one of the best characters, but in practice, players don't play him to his full potential, and because of that, Yasuo is considered trash, and this may not be changed any time soon.
UW often posts a wheelchair emote when he sees someone talking about Yasuo, because he considers Yasuo players to be mentally handicapped
