Hiding Bug Uncertainty Principle

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.

Corridor of Uncertainty

2. A line in cricket, when the ball pitches usually on a length, just outside the batsmans off-stump. It is such a good line that it leaves the batsman unsure of whether or not to play a shot, and usually results in either an edge, a play-and-a-miss or some other form of comedy cricket.

3. A dark alleyway.

4. A womans anus. Do you dare venture into the Corridor of Uncertainty?
Ooh, he's put that cross right along the Corridor of Uncertainty and caught the defence in one dilly of a pickle!

British slang for a scientist or technical expert, esp . when the speaker is not certain of the expert’s specific field of study. Not necessarily derogatory, but typically used by persons without a technical background. In the US, the equivalent would be “egghead”, “squint”, or “geek.”

Origin of the word is unknown. Started sometime in World War 2. Given the typical evolution of British slang, could easily have started because what these experts did was confusing or “baffling” to the common person.
According to the boffins downstairs, the murderer used a serrated blade.
