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.

Uncertain Times 

The mealy-mouthed, weasel-worded, chickenshit phrasing that brand advertising likes to believe is "reassuring" about massively negative global events, instead of using real words about what may be going on, like "pandemic" and/or "economic crisis" and/or "presidential incompetence".

Singular form: "(this) difficult time"

"In these "uncertain times", disposable toilet seat covers are more critical than ever, like airlines and vacation cruises. Remember, sometimes the only thing between you and a coronavirus droplet might be a Big Johnson Ass Gasket."

untertainment 

entertainment that fails to entertain

"Steps into Summer" is untertainment at its very finest, and will be warmly welcomed by those who watch TV with a shotgun in their mouth, trying to pluck up the courage.
(as quoted from TV critic Charlie Brooker)

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.

Uncertaint 

An adjective describing a time when people are freaking out so much they instinctively hoard toilet paper.

Stephen: look at all these assholes buying up more wads of TP than their bungholes can handle.

Adam: Who can blame ordinary humans in these uncertaint times. I’ve got a bidet but not everyone is so taint-forward.
