its got the stereotypical group of teens in it, the jock, jock’s pretty girlfriend, nerd guy, and the finale survivor guy. they go out into the woods during like fall season and mess with something that summons a killer like jason. the killer hunts them down and kills them one by one, im pretty sure either the jock or the pretty girlfriend die first, or both of them. the killer wears a mask i think, and has long ish black hair that almost always looks wet or greasy. the killer ends up in the finale survivors house hunting him down, and then i don’t remember the rest.
Could be one of the various Hatchet movies.
