<human>: Can you provide a brief rundown of the text in within 3 sentences?

So I saw (the popular ass grabbing vine on r/videos right now titled "What Would You Do?" that I can't link in the post) and even though it was meant to be funny, it got me thinking about what I would do in that situation or similar ones.

My girlfriend often gets comments and stares, some very crude ones, and I want to know a proper course of action. I am not a huge strong guy and I'm not aggressive or reckless, so I never would consider any sort of physical action, but I'm wondering whether my policy of ignoring the comments like she does is the right one. I want to stand up for her, but I don't know what is considered appropriate.

In the specific case of that vine, I have no idea what I would do. I would be scared, but absolutely livid. I'm looking to hear community comments on this subject. It really isn't tied to our age or relationship duration in any meaningful way so I would love to hear any input from any stand point. Thank you.
<bot>: Joke post made me seriously contemplate a proper course of action when dealing with people who flirt with my girlfriend or are crude with her. Looking to see what other people think and what they would do in those situations.
