Thou shalt not twerk.

That’s the lesson one California mother wanted to drill into her 11-year-old daughter’s head after she found out her daughter twerked at a school dance. Frances Hena of Bakersfield decided to publicly shame her daughter Jamie by making her carry a sign on a busy street that read: "I was disrespecting my parents by twerking at my school dance.”

Hena forced her daughter to stand outside and hold the sign up for two hours on Monday afternoon. She called a local news station to cover the public shaming, ABC News reports.

“I want her to realize that she is just a child and that she can’t do that,” Hena told ABC News.

Twerking, defined by Oxford Dictionaries as “dancing to popular music in a sexually provocative manner involving thrusting hip movements and a low, squatting stance,” has made headlines since Miley Cyrus’ performance with Robin Thicke at the MTV VMA event last month.

Hena thinks Washington Junior High School, Jamie's school, should have done something about it. “I haven’t heard anything from the school still, and it’s just ridiculous to think that’s okay at a school dance,” Hena said. “I’m also not sure my daughter realizes how seriously I take this.”

The disgruntled mom found out about her daughter’s twerking from a friend. “When she’s 18, she can do whatever she wants,” Hena said. “As of right now, that’s not something she’s going to be doing.”

Many drivers stopped to read the sign. Some laughed, others asking if Hena went too far.

“Every parenting [style] is different,” Hena said. “I mean, what am I supposed to do? Whoop her and get the cops called on me?”

The punishment is humiliating for everyone involved, Hena adds. “I think this is embarrassing, I do. I’m embarrassed myself for having her twerk at a school dance.”

Hena says the incident has inspired her to take a more active role in her daughter’s education. “I’m planning on going to her school a few times a week from now on just to make myself present there and for her to know that I’m not playing around.”
