Yeah, I have to say that's pretty awful and tasteless, the way he embarrasses her and how upset she gets. Not to mention it's on (live?) television. I get the sense from how shaken she is that she has some trauma history with tickling or something else.
I don't know what they were saying, and I'd be curious if anyone can translate.
This is not usually how I react to a tickling video or witnessing an incident, even if it's a non-consensual "vanilla" or mainstream incident, but more than anything this felt like watching an act of violence to me.
