What’s that KEKEKE stuff?
***
Ahh, it’s just an old, old Internet thing.
Short version: the South Koreans really love Starcraft, and when they post about laughter, the laughing gets translated as ‘kekeke’. So it’s a nerdier version of ‘lol’.
Nice one, thanks for the etymology tidbits, made me smile like not much else on this very long thread!
