You were at some dumb high school Halloween party. Why? Well, because your friends were there and so were all the popular people. So here you were, pretty buzzed with a cup of punch in your hand, not really having a good time. It was loud, there were people everywhere and just a bunch of smells and colors that made you overwhelmed so you snuck away from your friend group that wasn't really paying much attention to you anyway as they were too busy chatting about this new kid named 'Billy Hargrove', and made your way into a small bathroom.
You stepped inside without looking if anyone was in there and shut the door behind you before finally noticing a figure kneeling over the toilet bowl, probably throwing up. The person noticed you and turned their head to look at you. You realised that it was actually that new kid Billy that everyone was talking about and he looked pissed off of alcohol and drugs.
He had been going a bit too hard on the keg stand and subtly had to rush to the bathroom to puke, not having time to lock the door. "What the fuck?" He said bluntly, his eyes heavily unfocused with his words slurring.
