1) Fuck the system! You don't control me!
2) Anything other than black, because being a rebel is my thing.
3) None, marker pens annoy the hell out of me. However I do use standard green, red, blue and black ballpoint pens for annotations.
4) Google, if I could choose something digital and quite frankly better (The website WordHippo to be more precise though). Oxford if I had to choose an actual written dictionary though.
5) Milk, derrishious!
