Project Insomnia is many things, but in this context it is simply a "braindump" of whatever I happen to be thinking/reading/watching/doing at the moment. Parental guidance suggested.
Letters can be substituted for other letters that may sound alike. Using "Z" for a final letter S, and "X" for words ending in the letters C or K is common. For example, leetspeekers might refer to their computer "5x1llz" (skills).
Rules of grammar are rarely obeyed. Many leetspeekers will capitalize every letter except for vowels (LiKe THiS) and otherwise reject conventional English style and grammar.
