Saying GG _____ is actually pretty rude...
Now don't get me wrong you're allowed to be rude, it's not against the rules. It's just something I see more and more often.
When you say it you're generally pointing at one enemy and saying "If it weren't for you your team woulda lost because we're better than them" or "I'm better than everyone else here and if you hadn't stopped me..."
First off this is a team game, no one wins alone. Secondly it can be considered really rude to everyone else in the game and kind of a dick thing to say. On top of that you don't know the circumstances. Lose with some dignity.

I just got this game for example and someone (I wont say who so I don't have to bother blacking out names) said "GG Yi". First off Yasuo did more damage to our team with less gold, and fed our team less gold to top it off. Secondly he completely disregarded all other opponents and may or may not have known their situation. The Yi and Yasuo happened to both be much higher rating than others in the game. Also yeah their ADC didn't do great, not a whole lot of damage and had fallen behind on gold but I'm sorry 9/4/12 isn't bad for a bronze 3 surrounded by gold/high silver opponents no matter who is on their team considering the massive skill gap. I mean it's not like we did well against the high gold/platinum on their team.
IDK what MMR Lux was but 18 assists isn't bad, besides we were actively trying to feed off their bot lane while they tried to protect it. Heck even for the top lane Noc 5/5/14 is definitely a contribution, especially as a lane nocturne. It's a team game, they all contributed.
TL;DR No one has to be kind or nice, heck it's the internet we're all pretty used to this place being full of scum and villainy but it doesn't mean we shouldn't suck it up and lose with dignity or at least be nice.
