This law of nature states that if you see a gross bug in your room and it crawls out of sight, it could be anywhere in the room. It follows that there is a significant possibility it could be about to crawl onto you, and this fact will eventually freak you out.

Borrowed from the Heisenberg Uncertainty Principle, which states that both the position and momentum of an electron cannot be known.
I just saw a spider go behind the desk, and by the Hiding Bug Uncertainty Principle it could come out of nowhere and crawl on me at any moment.
