Y'see, when people see my username, the first thing that often springs to their mind is "past tense of shake". But boy, is that wrong! So now i will share my incredibly epic story of how i got this here username... Which, conveniently, has stuck for several years, occasionally being replaced by names with more or less similar pronunciation, such as "Shewk", "Schewk", "Scheouwk" and so on. Not in any forums, though, where I'm consistently known as Shook. And while it does share the initial letter with my first name, it has nothing to do with it. Now, on to the story...
I was playing a game called Crusaders of Space: Open Range, which is a Space Invaders-style game with much better graphics. In this game, whenever you had shot down a new type of enemy ship, you would get some information about the ship type, such as speed, armor and firepower. You also got the name of the ship, which more often than not included a nickname as well. So, i had just shot down a tough, blocky ship (the ship itself is irrelevant, really), and when i went to look at the ships info, i saw nothing less than a miracle written down in text... "Shook", the ship was called. Ever since i saw that, I've used that name consistently, not even knowing that it was the past tense of "shake" until much later. Also, the game is strictly singleplayer, so I've not taken the nickname from anybody. =P
And there you have it, the wonderful story of how i got the name "Shook".
