A 13-year-old male high school student was teasing an 18-year-old girl about her vaginal flatulence before being struck in his testicles, police said.

The Jan. 17 incident, according to a police report obtained by The Smoking Gun, occurred on a school bus that was traveling in Sugarcreek Township. The small Pennsylvania community is located about 50 miles northeast of Pittsburgh.

“The accused expelled wind from the vulva during coitus while at the back of the bus,” state police trooper Brad Jordan wrote in his report.

“The victim began to laugh and chuckled at the accused for her actions,” the trooper continued. “The accused approached the victim and elbowed him in the testicles.”

The girl was ultimately cited for harassment. No word yet on whether school officials plan to discipline the girl for allegedly having sex in the school bus.
