This may sound like a terrible vague sub-genre, but I shall elaborate. I had hoped to do a Fraternity/Sorority them, but when I was looking up movies that fell into that category, I had seen most of them and it left me with a list of about two movies. So I opened up the search a little and looked at other movies which mentioned Frats/Sororities, based on college kids and again I had seen most of them.
However, I figured that having a theme based about killing college kids has got to count, so that's what I settled on. I have a list of about 6 movies, I'm aware that one or perhaps two of them don't actually take place at a college, but supposedly make a thing about these being college kids, so what the hell. I've seen a lot of horror movies, it's hard finding ones which will fit into a particular sub-genre that I haven't actually seen.
We'll see how many I end up with at the end of it, sometimes I managed to find other movies to add to the list, sometimes I discover the copy I have is unwatchable or is in Korean with no subtitles or is in fact the completely wrong movie.
