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

This story is from a friend of mine while we were in college.

We were in the computer lab at our university where everyone understands is a place for studying, working, etc. It is NOT a place to blare your shitty music. Anyhow, this kid comes in and starts listening to some really bad music, playing it really loudly. 

My friend, who was working on a midterm project, asked the kid if he wouldn't mind turning it down as all the other 20 people in there would like to study as well. The kid literally stared at him for 5 seconds then sneered. Wow buddy.

So eventually after another 20 minutes of this, the prick gets up and leaves. However, he did not sign out of the computer or close his browser. More importantly, he did not log off the University in-system email. So my friend hops on this kid's computer. Since this prick was still logged in, he was able to select each course the kid was in, and send out mass emails to the whole class including the professor.

All the emails were inappropriate, but not raunchy or overly rude, but my favorite was, "Hey guys, with midterm test coming up and it being curved, let's all just not show up. He will have to give us all an A!" Since the email included the professor, I can only imagine what responses he received. 

Later that week we saw the kid walking down campus. He locked eyes with my friend and gave him the look of death. It was pretty great.
<bot>: Asshole plays music in the computer lab, my friend uses Asshole's account to send fake emails to Asshole's classes and professors saying everyone should skip.
