X)

x) is a meme brought on by the favored emoticon of a widely-believed-to-be-one-fry-short-of-a-happy-meal user named mortenmkl, who was banned for xraying and for being a dumbass x)

It was originally just an emoticon constantly used by morten until some mods, namely Eagle, AnonymousPepper and ff7perfection coordinated the heavy usage of x) to the point that it was used as a running gag whenever somebody wanted to mock him - which was quite often, as pretty much nobody liked him x) He never caught on, of course, the dumbfuck x)

It's now used whenever talking about something or somebody stupid, whenever speaking of him, and as a method of quickly identifying morten in various comics x)
