Pesky

There's a pesky wrinkle on my shirt that I just can't get the iron to remove.

"Luigi, look! It's from Link. Let me read it: 'Dear pesky plumbers, I'm under attack by the evil forces of spaghetti! Save me!' We gotta save Link!" "I'm the traitor, and you must die!" "Shit!"

That pesky imp must be punished.

All of today’s nuclear power plants make energy by the splitting of uranium atoms — which creates a lot of useful heat but also a lot of dangerous and deadly nuclear waste. The opposite process — fusion — also creates heat but with hardly any pesky radiation. The problem is that fusion is way more difficult to achieve. Scientists from 35 nations, including the United States, Russia and China, are painstakingly trying to solve the problem.

I was bitten by a pesky midge during our camping trip.

Stay out of my yard, you pesky kids!

That pesky dog is barking again.
