A video of the mum, who hasn't been named, was uploaded to Twitter by London Streets, and it shows the mum livid with rage over her son's alleged bullying.
‘Do you know who I am?' she says.
‘No? No, I’m [child's name] mum, yeah, yeah puss yo, I’m [child’s name] mum.’
As the woman gets closer, a child can be heard behind the camera saying: 'You can't touch him,' to which she replies, 'You bet!'
Filmed outside what looks like a school, the woman paces away from the camera before tying her hair up and re-approaching the boys.
'Touch my son again and I'll rip you ****ing face off!' she says. 'I'll rip your mum's face off, your dad's face off... touch him, I dare you to.'
Since being posted two days ago, the video has had almost 45,000 views. Most people commented underneath that they agreed with and applauded the mum's direct approach to bullying.
'Right, so i'm not usually one for being ok with this but it was the moment she took her hat off and tied her hair up to face this boy down is when i knew this bully had done something really bad,' said one woman.
'I bet her son's not had any problems since. So all well and good,' said another person.
While others thought the mum took it too far.
'Can understand her anger, but seriously?! Wrong approach. Completely inappropriate,' wrote one woman.
What do you think - would you confront your child's bullies this way?
