Found in World of Warcraft, 'lol', typed by somebody on the Horde faction,
will show up as 'kek' to somebody on the Alliance faction.
It started as the Swedish translation of 'lol', and was adopted as the Orcish translation of 'lol'. It is often used in other games as a synonym for 'lol' in 1337speak. People use the word 'kek' so that only fellow '
1337 pr0s'
will understand them.
