LAS VEGAS -- One mother considers it a form of bullying, but some students call it a middle school tradition.
It is known as 'slap-ass Friday', where students slap each other.
YouTube video shows students slapping each other on their behinds, which is what happens on slap-ass Friday.
It is not just a Las Vegas valley problem, but locals are speaking out about it.
"I am just outraged. I feel like I'm sending her to be into a pack of wolves everyday," legal guardian to a seventh grader Denise Delucia said.
Delucia says she is the legal guardian of a seventh grader at Escobedo Middle School and heard the seventh grader talking about what happened to her in the school hallway.
"I actually am going to keep her out of school until the situation is resolved on Fridays. I'm not letting her go to be accosted on Fridays, that is not acceptable," Delucia said.
