A yearbook prank by a Missouri girl could now bring federal charges upon her.

Seventeen-year-old Kaitlyn Booth, a junior at Hickman High School in Columbia, Missouri, is in trouble for changing a classmate’s name in the school yearbook.

At first you may think "it’s not THAT big of a deal"! But the girl allegedly changed her classmate’s last name to “masturbate” instead of Mastain.

Of course, the yearbook was already printed when it was discovered, and the school declined to make about 700 new yearbooks that would cost about $41,000. But, stickers were printed with the student’s real name so that the students could place them into each yearbook.

The girls are not friends, and Mastain said that she was shocked to learn of her peer’s arrest. Mastain also stuck up for Booth, saying that she doesn't think the prank should affect Booth for the rest of her life.

Booth faces charges of felony first-degree property damage and harassment.
