Many women will know the fear of being put in an uncomfortable situation by a stranger, whether they're trying to strike up an unwanted conversation, or engaging in downright harassment.
But one TikTok user has shared a video showing that sometimes it takes the attention of someone else getting involved to make a creepy man back off.
In a video that has been viewed over 33 million times, Brandon Robert started recording the moment he noticed a "weird man" was making another shopper uncomfortable whilst in a shopping mall.
"I'm going to pretend I know her," he wrote, filming himself walking over to the woman and her harasser.
In the clip, Robert pretends he knows the girl, exclaiming "hi!" and asking how she is.
The woman responds straight away, going along with the ruse.
When Robert says his aunt is there, the girl replies, "Aunt Claire?"
"She knew I had been watching and listening to what the man was saying to her and realised I was trying to get her out of the situation," Robert later told Buzzfeed. "She went along with me 'knowing' her immediately."
The pair walk away together, before off camera the woman can be heard saying "thank you so much" to Robert, and telling him the seemingly intoxicated stranger was asking her to "go back to his place".
"She was very appreciative and said I may have just saved her life," Robert told Buzzfeed. He added that after the encounter, he walked her out of the store and to her car.
The video has proved an important reminder to others to keep an eye on those around them, and has inspired others to step in when they see strangers in uncomfortable situations.
"Guys please do this," one woman commented. "It really does help because unfortunately, these men will only leave a girl alone when another man comes."
"Thank you man, we need more of these," another person wrote. "More awareness."
Others asked if "Aunt Claire" could now be a codeword.
"Aunt Claire came in clutch," someone joked.
