The loser sends a "GG" to show that you are better in this game, and I am convinced that I lost. Later, the word "GG" gradually evolved into the meaning of "admit defeat" by domestic netizens, mostly because the loser played "GG" in the game and was ready to admit defeat.
The origin of this stalk
The stem originated from the anchor of League of Legends, and the electric baton itself got stuck or the teammates couldn't fight. When they can't fight and are ready to surrender, they say "it's from me", which means giving up. Later, the anchor of Tiger Tooth League of Legends used the word "I sent it" at high frequency, which caused many netizens to use it.
"Send" now often appears in competitive games, meaning to show appreciation to opponents, meaning "I give up if I play well", and later it is often used to mean "failure" in real life.
