with his mouth wired shut after being in a car accident, Kanye had to resort to a liquid diet consisting of Boost and Ensure, which have many vitamins and minerals and are good food substitutes but many people don't like the taste of.
dynasty sign is a diamond-shaped hand gesture used to represent the Roc-A-Fella Records crew, and Kanye's girl has been a fan of Roc-A-Fella (and Kanye, before he became famous) because she used a similar triangle sign as a member of a Delta sorority
Kanye is comparing his face after his car accident to that of Tom Cruise in the movie Vanilla Sky. In the movie, Tom Cruise's face became disfigured when a car he was riding in was driven off an overpass by the character played by Cameron Diaz.
since he was just in a car accident, Kanye will need a lawyer to protect what's in his "safe" (probably not an actual safe, more likely just referring to all his money and valuables) safe (protected from being taken in a lawsuit).
Kanye (when his mouth wired shut) couldn't eat pancakes or other solid foods, so he has to just sip the syrup. Instead of syrup he uses the word "sy-z-rup" which is slang for drinking cough syrup to get a buzz.
Kanye West is saying that just breaking his jaw in such a serious car accident is nothing and he is unbreakable (unlike Samuel L. Jackson in the movie Unbreakable who plays a character Mr. Glass whose bones break very easily).
