I think that's rape, Shaun.
If she wants to sue him, it will definitely qualify as sexual assault. Seriously - that's a risk I wouldn't take under any circumstances. She doesn't even have to press charges and he could find himself in jail.
Who? What? Me rape? Who? Still confused...
No, not you, the guy in the video pantsing the girl. It wouldn't be rape, but if someone saw it happen and turned him in, it would be investigated as sexual assault. Probably wouldn't lead to indictment, but would make for some uncomfortable and expensive hours getting interrogated and paying an attorney to sit with him. Once upon a time, it was a joke. Now...it's sexual assault.
