If both players exchange this equal recognition at the end of the game, they leave in appreciation of each other.
There is a difference between saying gg AFTER your opponent bows out, and saying gg BEFORE your opponent.

Example 1:
Player 1 (the loser): gg
Player 2 (the winner): gg

This example is a form of good etiquette. It's like highfiving the other ball team after a game.

Example 2:
Player 2 (the winner): gg
Player 1 (the loser): gg

Player 2 is an example of bad manners. It's like saying "you haven't accepted defeat yet, so I'm going to pre-emptively throw it out for you because I owned you so hard." This is what's called an Offensive GG.
