I walk up in the world and cut the lights off
When you cut off the lights, it’s completely dark and implies no one can see you. Wayne saying he’ll walk up in the world means he has the attention of the world on him, but since it’s dark, he will surprise the world whenever he chooses to strike because it wouldn’t have seen it coming and therefore will be thoroughly surprised.
Could possibly be referencing to 1997 film The Devil’s Advocate
Don’t get too cocky my boy. No matter how good you are don’t ever let them see you coming. That’s the gaffe my friend. You gotta keep yourself small. Innocuous. Be the little guy. You know, the nerd… the leper… shit-kickin' surfer. Look at me.
