Go Gort

Not to nitpick, but it was "Gort....Klaatu Barada Nikto."

Yes. Patricia Neal's character said it to Gort (so that he would take her into the flying saucer instead of vaporizing her).

Not a problem. Enjoy the second-half of your weekend!

"Klaatu barada nikto" is what Klaatu told her to say. She just says "Gort" because she ahd heard Klaatu call the robot that name.
At 42 second mark in this vid is the scene from the movie where he tells her what to say:

We're both right. You're right, that's what Klaatu told her to say. But soon after, when she confronted the robot, she called it by its name.

Google "patricia neal confronts gort"

Yes, I know she called it by it's name, and then repeats the phrase twice.

Great! We both know the movie.
