uncertainty 

The state of being in which an outcome is both unknown and can not be predicted by any means.

The uncertainty of his behavior leads most people to believe that it's random.

Uncertainty 

the state of being uncertain.
something that is uncertain or that causes one to feel uncertain.

"have we discussed doing counseling before the wedding?"
"Ian’s trying to say I shouldn’t pay my fiancés bills. Do you agree with that?"

uncertainty principle 

1. States the position and momentum of a particle cannot be simultaneously measured with arbitrarily high precision. This is a crucial concept that is a part of quantum mechanics

2. The modern-day version states to never judge a girl's looks from a distance greater than or equal to 50 feet.

The uncertainty principle seems very straightforward.

Man, I was drunk last night at the party and the uncertainty principle totally slipped my mind. I swore he looked like a girl.

Uncertainty Principle of Science and Epistemology

An adaptation of Heisenberg's insight that observation affects the observed, extended to science and knowledge itself: the act of studying a phenomenon inevitably changes it, and there are fundamental limits to what can be known simultaneously. The Uncertainty Principle of Science and Epistemology suggests that in studying complex systems (societies, minds, ecosystems), the very act of measurement alters the system. Moreover, there are trade-offs: the more precisely you know one aspect, the less precisely you can know another. You cannot simultaneously know the position and momentum of a particle; you cannot simultaneously know the structure and dynamics of a society; you cannot simultaneously know the content and context of a belief. Knowledge has fundamental limits—not due to poor instruments, but due to the nature of reality and the knower's inescapable role in it.

Uncertainty Principle of Science and Epistemology "Study a society, and it changes because it's being studied. Measure a mind, and it's altered by the measurement. Uncertainty Principle for Science says: there are limits to knowing, not because we're bad at it, but because knowing changes things. The more precisely you track a variable, the more others blur. Science isn't broken; it's just uncertain—and uncertainty isn't failure, it's physics."

The Big Time Rush Uncertainty Principle 

That feeling of dread one gets when they are fearful of leaving their house because Big Time Rush will be having a live concert in their front yard.

Guy: Do you want to go out later?
Girl: No, I can't leave my house because of the Big Time Rush Uncertainty Principle.

eye contact uncertainty 

what happens when you are not sure if someone is making, or is trying to make eye contact with you. generally occurs in crowded places over a distance.

is that hot guy way over there smiling at me? i am plagued with eye contact uncertainty.. D:

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.

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.
