Paris Gray, the senior class vice-president at Mundy's Mill High School in Clayton County,used the elements barium, carbon, potassium, thorium, astatine, arsenic, sulfur, uranium and phosphorus to spell out "back that ass up" in her yearbook quote.
"When the going gets tough just remember to Barium, Carbon, Potassium, Thorium, Astatine, Arsenic, Sulfur, Uranium, Phosphorus," Gray wrote in the yearbook.
After yearbooks were distributed, Gray was hit with an in-school suspension and barred from participating in a senior walk event.
"I think their reaction was beyond what it should have been because nobody understood it," Gray told WSB TV. "Basically, it was me just saying start all over again. You have to go back and start all over."
Gray was also supposed to give a speech at graduation, an honor that has since been revoked by school administrators.
"It just completely destroyed me, and my mom's been telling me don't let it ruin my happiness but it's like really taking a big toll," Gray said.
