The football players at Conestoga High School had a nickname for the rituals they performed each week, according to prosecutors.
Some players avoided the locker room that day, when players considered certain sexual behavior permissible.
The hazing at the elite Chester County public school, routinely ranked near the top academically in national ratings, escalated into assault one day last fall, authorities said Friday.
Three seniors, including a team captain, grabbed a freshman they didn't like, who was trying to leave the locker room during a hazing ritual. Two held him down, while the third penetrated his rectum with a broom handle, officials said.
