GG WP is an abbreviation from the world of computer games, which stands for "Good Game, Well Played" , which means "Good game, played well" in Russian. This abbreviation is usually written at the end of the game to admit defeat and congratulate the opponent with a good game.
Often lazy gamers forget or do not want to change the layout of the keyboard and write this phrase in Russian letters: YY , that is absolutely kosher in terms of world Zionism. By the way, at the beginning of the game they usually write each other "GL HF" , that is "Good Luck, Have Fun", and in Russian translation "Good luck, have fun with me here!", But this is a completely different story.
I ask you a rink and all the best, my dear zadrot!
