A mum told her daughter's alleged bullies she would 'f up their adult relatives' in a furious rant inside a classroom.
Christian Tinsley threatened pupils at Niguel Hills Middle School in Laguna Niguel, California, telling them if they bully her girl they can send their mums 'her way'.
She told them to leave her daughter alone, saying that she was the 'big bully' in the confrontation on Tuesday.
Footage of the incident shared with CBS2 shows the mum standing in front of a classroom and appears to have been recorded by one of the students.
The mum said she understands she could have handled the situation differently but was 'at her wits end' when her daughter cried to her and made a comment that 'if she wasn't as strong as she was, she would have killed herself'.
Ms Tinsley was escorted out the building after the classroom teacher sent for help.

"If you all bully my daughter, if you look at her the wrong way, if you breathe the wrong way, send your mum to me,” the woman can be heard saying in the video.
"Sisters, aunts, anybody over 18, I’ll f them all up. Do you understand me?"
As she continued her rant, she asked if they all thought they were bullies, and told them to understand that she was the 'big bully'.

Ms Tinsley claimed her daughter had been telling her for months that she was a victim of bullying by boys at the school.
She claimed the bullying was both in person and over social media - and that the comments included racist, sexist and derogatory content.
The mum said that she felt like she'd tried everything and the issue hadn't been resolved and so went a step further to deal with the situation.
She has been banned by the school as detectives investigate the incident.
On their televised report of the incident, CBSLA shared a written statement from Niguel Hills Middle School Principal.
The statement to families attributed to Tim Reece read: "When a parent or student shares concerns about bullying or harassment with administration, teachers or staff, they are immediately investigated at our school site and both students and their parents are contacted."
