<human>: Can you summarize the given text in a few sentences?

I was enjoying the front row of a NetSky show, and let some chick up into the front for a few minutes. Things were nice, then she left to get more drinks.

Enter sweaty tank top guy and his giant drunk girlfriend seizuring their way to the front to the sound of music. I spent my time trying to elbow the guy in the ribs as He tries to push by. I had leverage from one hand on the stage, he was not getting by on my watch.

Now comes the fun part. The chick I let in front of me earlier comes back and is dancing (facing the wrong way) behind me. Things are looking bad for her, and then she bent over like she had just run a long way. I watched her puke all over the sweaty tank top guy's shoes and feet. He was so gone he just kept dancing. I didn't say a word to him about the mess, he stayed oblivious. I soon left the scene, as I was worried about the expansion of the mess.
<bot>: Sweaty guy danced up on me and spent the rest of the night partying in a puddle of puke.
