So I rented this movie about 5 years ago and can't remember the title for the life of me! It probably was made no earlier than the 90's.
The movie starts out with a group of friends who want to scare one of their female friends. They stage a murder to scare her but something goes wrong and of course someone really ends up dead. For the rest of the movie the remaining friends are chased by a serial killer who may have used gardening shears as a weapon. There are several funny moments in the film once where a guy innaccurately states the time and says something like "whatever I'm not good at math" and his friend says "that's not math it's telling time". Also, a guy attempts to slide over the roof of his car and fails miserably.
In the middle of this movie there is like a mini movie of it's own about tiny monsters that awaken in some guys apartment after he steals an ancient artifact from a museum. The only way to stop the tiny monsters is to shine light on them so the guy arms himself by taping flashlights all over his body and wearing a headlamp. Somehow he ends up in the basement and of course all of his flashlights go out and he gets crushed by a washing machine.
I know this is pretty vague and possibly inaccurate but I'm hoping someone else has seen this movie and can bring my unsuccessful internet searching to an end! Thanks in advance for your help
