In Hangul, the Korean written language, people express a laughter sound with repetitions of the character "ㅋ", similar to the "k" sound in English. Since early versions of StarCraft did not support Hangul, Korean players would use a romanized spelling—hence, kekeke was born. The phrase is a phrase similar to the English and French "hahaha", Spanish "jajaja", Chinese "hehehe", or Japanese "fufufu"/"kukuku".
