It's not about me being oversensitive. It's not about how toxic the phrase is. It's just shit sportsmanship. This is a sport. If ever someone said this after an MLB game, you can bet there would be a bench clearing brawl that results from it. Just because you're a coward that can only confront people from the anonymity of your keyboard doesn't give you the right to be a shit person. Stop with this cancer. NOW.
Edit: for all the people who keep saying that GGEZ is fine because it's not punishable:
>While it’s alright to celebrate, make sure that you keep any gloating (or any other mode of self-indulgence) out of all chat.
Straight from the Summoner's Code. It's punishable.
