A mother will do anything to defend her children. Occasionally, of course, that impulse can go a step too far.

In Laguna Niguel, California, a video taken by a student shows a mother barging into an unsuspecting 2nd-period classroom and offering kick the a** of anyone who messes with her daughter.

Mother Threatens Students At Laguna Niguel School Over Bullied Daughter youtu.be

The video was taken in an 8th grade classroom at Niguel Hills Middle School, where a mother entered without warning and began shouting at the students:

"Don't post nothing about her. None of that. Y'all think y'all bullies? I'm a big bully, ok?"

Believing her daughter was being bullied, the mother instructed the other students to send her their older relatives for a smackdown:

"She's a girl. Y'all are boys, ok? If y'all bully my daughter, if you look at her the wrong way, if you breathe the wrong way, send your mom to me. Sisters, aunts, anybody over 18, I'll f--k them all up. Do you understand me?"

The mother couldn't have been any clearer:

"Leave my daughter alone and I'm not gonna say it again."

While she was there, the mother also decided to hand out some coupons which she had printed before visiting. They read "Free A-- Kicking," and could, of course, be redeemed with her at any time:

"A-- whoopings. A-- whoopings. For free. For free!"

Many Twitter users, however couldn't help but throw their support behind the mother:

One student told CBS Los Angeles what the experience was like:

"It was actually kind of scary, but then she was like, all talk. So I thought it was like kind of funny towards the end, but at first it was scary because some random person comes in the class, and starts yelling, like I don't know what your initial thought would be."

Police are now investigating the entire situation. One can only hope they don't incite the vengeful mother's wrath.
