In the latest bullying video, students are shown threatening victim before slapping her.
Another video of female Malaysian students tormenting a girl has surfaced.
This time, the incident took place in a school toilet.
In the undated clip, the schoolgirls are heard demanding money from their victim, and then taking turns to slap her.
The victim stayed silent throughout.
Said the contributor to STOMP who discovered the video: "I hope the video will make these people reflect on themselves, for what they have done is truly inhumane."
"Imagine what the victims of bullying go through.
"I would like to urge all those who are still silently suffering as victims to stand up.
"Tell an adult, whether it's your teachers or parents. Your future is on the line."

This is the most recent video to emerge on female student-bullies.
Malaysian paper The Star on Monday reported on a video of a schoolgirl being bullied by her classmates that has shocked netizens.
In the clip, the tormentors cut the student's hair, and attempted to strangle her with a tie.
The bullies in the widely-reported case have since apologised to the victim. They were suspended from school for 14 days.
