What does the boy mean by GG?

1. In the game, this GG means a good game, which means that both opponents and friendly forces are very good games, but now it is often used to ridicule that friendly forces are strong, and games that are not over but have confidence in winning will also play GG. 2. In life, between male and female friends, when boys and girls are together, it may be said that GG may be your's friendship or affection, and it has reached a certain level, as if the game is coming to an end. 3. When boys and friends are together, they may say GG when joking, play games or make fun of each other. Pure hands, forgot to adopt, thank you.
