GG

GG is commonly used in online gaming, such as chess or Starcraft to say "good game." It is often typed at the end of a match to congratulate the other player.

GG (usually typed "gg") is considered a respectful way to end a match rather than simply surrendering. In some cases, "gg wp" (good game, well played) might be used to show extra respect to the opponent.

In pro leagues, players often type gg and then immediately surrender. However, in lower leagues, the winning opponent is often given a chance to type "gg" in response. Typing "gg" and then still trying to win the game is considered bad esports etiquette.

If you have not just finished playing a game, GG likely stands for "good grief." This acronym is used to express surprise and frustration.

Peanuts character Charlie Brown popularized the phrase "good grief," often using it to decry TMW things went wrong in his life. In the digital age, online sadsacks, who may be as down in the dumps as good ol' Charlie Brown, have shortened "good grief" to GG.
