Killing the butterfly 

Cutting when you are taking part in the butterfly project. The rule is that if you cut yourself while you still have the butterfly drawn on you, the butterfly will "Die."

Person 1: I'm so mad at myself.
Person 2: Why?
Person 1: I killed the butterfly.
Person 2: Please, stop cutting. This is the second time you've been killing the butterfly.
Person 1: I know, I'm sorry.

Killing the left lane 

When one vehicle is traveling in the left lane but not passing anyone thus blocking other vehicles from passing, causing a road hazard, and breaking the law.

This guy is totally killing the left lane. How is anyone supposed to get anywhere when the passing lane is being blocked by this clown?

You're killing me, Smalls 

Line from the movie "The Sandlot," meant to show extreme frustration towards someone's ineptitude or clueless-ness, sometimes both.

"What's American Gladiators?"
"You're killing me, Smalls!"

"Johnson, did you back up those files like I asked"
"Umm,no, sir. I forgot"
"You're killing me, Smalls!"
