1.First of all, the group of friends consists of exactly who you think it would: The funny guy, the guy who knows everything, the partier, the lush, and the virgin.
2.Parents are severely disconnected from their child's life.
3.Someone just has to wander off and investigate a strange noise.
4.This person will also shout "Hello?" or "Is anyone there?" into the darkness, hoping for a response.
5.The main character is portrayed as an innocent, do-gooder who doesn't really seem to fit in with her group of friends.
6.Yes, "her." The main character is (almost always) guaranteed to be a female in her late teens or early 20s.
7.The aforementioned character is also the last one standing. Always.
8.The "best friend" of the main character is a major partier and isn't exactly the sharpest tool in the shed.
9.The car won't start at the same exact time the killer is two feet away.
10.There also always is no cell reception when someone is trying to make a phone call.
11.A character can be running away at full speed, and yet the killer will still manage to catch up to them.
12.Speaking of running away, someone will run away and suddenly trip and fall over something...
13....and will then hesitate for a few seconds before getting back up, while looking the villain in the eye.
14.Having sex means getting murdered. No questions asked.
15.And being a virgin means making it through the onslaught.
16.While a bullet to the chest would kill a regular human being, it most certainly doesn't kill the killer.
17.It's deemed a good idea to "split up."
18.Something pops up behind someone who's closing a mirror cabinet.
19.And last but certainly not least, the protagonist has to say one line right before attempting to kill the villain.
