Another way of saying that you are untouchable and put everybody else to shame. Basically means you are unstoppable because if a person or thing can't see you they can't catch and/or attack you. Even though you are entirely visible it is a way of telling somebody that they can't fuck with you and they are not on your level.
Person 1: "WTF! You beat me a Halo again!?"
Person 2: "Damn straight biatch..."You can't see me!"
