Kek (also known as Top Kek) has been described by some as being /s4s/'s "light and freedom" and is a meme created on /s4s/ in May '13. It revolves around posting pictures of a Turkish snack-cake produced by the ETi food company known as 'topkek' and replying with "kek". It is also the next step in the natural evolution of the top lel meme.
Some willclaim that the origin is from WoW as an expression/phrase, but as that is a completely different context than the meme's context of a turkish snack cake, it is obviously untrue.
