Tiktok nut shot prank?

So I have a very hot girl friend (not girlfriend, pretty sure she friendzoned me) and 3 days ago I was at her house with her sister and they told me they were curious who had the highest BMI. So they took a measuring tape and measured each other. Then when she measured me she let the tape go and it hit me right in the nuts very hard, I fell on the ground. She then said she was sorry and it was for her tiktok and she had put a camera to film it all? her sister was laughing the whole time. Should I allow her to post something like this? Is she using me cuz she doesn't have a boyfriend or a brother to do this to? And I heard a bit about tiktok, they really hit each other in the groin for views? Never saw such a prank
