A high school graduate from Oklahoma who was named the school's valedictorian is being blocked by administrators from receiving her diploma because she used the word "hell" in her graduation speech.

According to Kaitlin Nootbaar's dad, David Nootbaar, the Prague High School alum's speech was inspired by a scene from Eclipse, the third film in the Twilight Saga franchise.

He told Oklahoma City's NewsChannel 4: "Her quote was, when she first started school she wanted to be a nurse, then a veterinarian and now that she was getting closer to graduation people would ask her what do you want to do and she said ‘How the h*** do I know? I've changed my mind so many times.'"

The school gave no indication that it disapproved of the language until it was time to pick up the physical diploma.

"We went to the office and asked for the diploma and the principal said ‘Your diploma is right here but you're not getting it. Close the door we have a problem,'" Nootbaar told the NBC affiliate.

The school would only agree to hand over the certificate if Kaitlin issued a formal apology for her actions, but she has so far refused to do so — a decision her family supports.

"She earned that diploma she completed all the state curriculum," said Mr. Nootbaar. "In four years she has never made a B. She got straight A's and had a 4.0 the whole way through."

The school would not discuss their decision to deny Kaitlin her diploma, calling the matter "confidential."
