gg is arrogance

Too soon.

hatters gonna hate,  saying good game is much better then saying gg, k

Hatters go mad working with the chemicals that separate the guard hairs from the underfur, for only the latter is useful in the making of hats. This madness, however, need not produce hatred.

Every time beat your opponent in a match, I often receive word "gg". What is meant by this word? Does my opponent is angry? Reason "ggrr" the sound of an angry tiger range

You hit that one out of the park, @Ziryab!  More power to you.    

So I guess then that hatters gonna hat...

Or something like dat.

Always check, it might be mat...

Hater's gonna hat too:

My hat is nefarious:
 

Hatlarious

Where's the GG hat?

I'll grab a patent on that asap.

Saying good game means good sportsmanship, nothing more and nothing less. It's called chess etiquette.  Learn it. 

Too late. 

Ok too late! Lol!

I've been teaching chess etiquette since the ninth century. For many hundreds of years, folks said thanks for the game. This whole gg thing came about in the last ten years. It does not have the same meaning as thanks for playing. It is lazy, and it relies upon depriving words of the meaning they once had.

...or else!

Stupid modern people!  They're all nefarious!
