Why? Why can't you just not be creepy? Go about your day, don't grope anyone, don't touch anyone & mind your own business.
I'm so happy this girl kicked this dudes booty after he touched hers. I used to work for this dude who would always spank me, sort of like chandlers boss on Friends:
I had to tell him that it made me uncomfortable and he reluctantly stopped.
Anyways, here's the video. Good for her!
