Apparently the guy who hit her noticed the bottles she was throwing, he also noticed that she was lighting m-80s and dropping them in the bottles before she tossed them.
And that's why he gave her the sweet chin music
I'm sure she was just offering him a glass of wine
In no way condoning anything about this vermin. She went trolling for contact and found it.
However, in the photo above, there a bottle by her left hand. Also note the photo shows her wearing a hat.
Here is a video from Liveleak, in this video, which is the same as the gif above, there is no bottle and no hat.
