PSA: Saying "GG EZ" or phrases alike is a reportable offence, no matter how you sugercoat it
I do not understand why some people think that saying "GG EZ" is "just a tease" and "does not do anything". It's not just a tease. It's adding insults to the injury after the losing team is defeated. It's just toxic. I don't care how "minuscule" the amount of toxicity "GG EZ" contains. It's unsportsmanlike and passive-aggressive, period.
We do not need to get told how horrible we were in a match. We get it. You won the match. You defeated us. Saying "GG EZ" achieves nothing but stroking your sadistic ego. If you say so you are either an immature prick or you suffer low self-esteem. Either way it's not okay. It serves nothing but ruining sportsmanship and letting everyone on your team and the enemy team know you are despicable and asinine.
[{quoted}](name=Riot Lyte,,realm=NA) In saying this, looking at the data, "GGEZ" is considered a negative term, and is reportable. Players generally agree that the phrase is rarely used in a positive context, and is a pretty sour way to end a match.

The only acceptable circumstances of saying "GG EZ" are, for example, when you are losing. It's nothing short of comedic when you are saying so as a member of the losing team. Always use "GG WP" to show that you have common courtesy, when you absolutely have to communicate with the enemy team.

Edit: The point of this post is to tell people it's not okay to say "GG EZ" unless you are doing so for comedic purposes like I mentioned in the post. I just think it's condescending and unsporting, and to top it off, childish. My patience or tolerance for people saying so has nothing to do with the point of this post, so if you are looking for a fight on this, I suggest you walk away because "whoosh, that's the sound of the point flying over your head".
Edit2: Some of the comments here are pretty on point. While people can argue how we should grow a thicker skin and be tolerant about it (In my opinion, not retaliating and reporting them after the game is already being tolerant about it), in saying "GG EZ", gloating and humiliating your opponents, you are telling people that your maturity is of a juvenile. Childish and pointless gloats like these only further prove that you are too immature to properly and courteously socializing with other human beings, let alone acquainting them. Before you say "I only do so when I hide behind the screen as an anonymous person", let me tell you that it doesn't justify this at all. I don't know why simple courtesy has to be taught in League of Legends Boards and why some grown adults here still do not understand the importance of sportsmanship in any (e)sports games. More importantly, news flash: professional athletes in various sports can be punished for committing unsportsmanlike offences. It's not something out of the blue.
Eh. GG EZ is just douchy. It isn't even smack talk, it's the equivalent of an elementary school playground where the winner sticks his tongue out, "Neener neener neener, I won and you're a peener".
It's childish and does nothing but enable gloating. Bantery smack talk is one thing, but GG EZ is just the pointless taunt of a child who is too immature to handle adult conversation and emotionally healthy competitiveness.
When i was little we called it being a "bad winner". Gloating and going out of your way to humiliate the opponent, refusing to be gracious about the victory. That's really the gist of it. GG EZ is just being a bad winner.
Smack talk happens during and maybe before a match. Not after. After the game you shake hands and typically compliment the enemy team for their efforts; regardless of how their performance was.
You say that people shouldn't be insulted by something as simple as that, when literally the only purpose that phrase even has is being disrespectful to the other team. You might as well say it's stupid to be insulted by insults.
Edit: Apart from that, it's not like LoL is the only sport where unsportsmanlike behaviour is punishable.
