YHS

Online poker players use YHS to stand for "your hand sucks." You can use this acronym whenever you want to tell another player that their hand is absolutely terrible.

Most often, you'll see YHS used in online poker forums. In these forums, players often post detailed breakdowns of their hands, plays, and thought processes, to receive feedback from other players. If you see a lot of YHS responses to a hand breakdown, it means the player likely should not have played that hand.
