You took too long when dragging your finger across the keyboard to type "qwertyuiop". Or you got so bored you managed to find a new keyboard sequence. qwertyuiop, except with a "[" at the end
When your bored on a Saturday morning, and you type the whole keyboard seeing what comes up. Well here you are! Looking my definition, because you are simply bored :]
Only typed when you are monumentally tired and bored that you wanted to typeqwertyuiop\asdfghjkl;'zxcvbnm,./ but accidentally hit the enter key on your keyboard.
Bob: Ok I've already tried qwertyuiop, I've already tried qwertyuiopasdfghjklzxcvbnm. How about qwertyuiop\asdfghjkl;'zxcvbnm,./ yea thats cool. But what if I tried to hit enter?
