There were countless amount of this slasher films with simple plots, maybe we should have a rough draft scripts of slasher for Incels, lol?
Here is CHAD UNDEAD, or CHAD NOT DEAD, or whatever corny 80's title.
And some poster slogan like: "IT MEANS NOTHING IF YOU SURVIVE. YOU ARE ONLY ALIVE IF YOU FUCK" or "SURVIVE TO FUCK. FUCK TO SURVIVE".
There was a dude named CHAD. He was going to have sex with Stacy and to invite her on prom, but he got in the carcrash and lost his looks. After he got of the hospital, everyone stayed away from him, Stacy rejected him for other dude that was his friend (let it be Matt). Chad went killing spree on the prom when his Stacy started to fuck with Matt in the toilet and killed him while injuring Stacy.
Stacy run away, Chad started to kill everyone, but later was shot by security.
Many years later, there is another prom in this typical suburban city. Main heroes are incelish dudes trying to get girls plus some current jocks leaded by Matt's son.
Killings start again, seems like CHAD grave is empty, and now he is CHAD UNDEAD returning to ruin it all again for everybody!
Some other characters - Stacy that rejected him, now she is single mother - she got pregnant that day in the toilet on prom from Matt.
Chad wants to find her and kill her and her son, because he thinks it should be his prom fuck back then, and it is should be his child.
Plus we would have police officer that shooted Chad, and Chad would also like to have revenge.
And Incels need to unite with jocks, and police oficer to fight against CHAD and also out compete each other for Stacys by killing one another too. For example - incel kills jock, jock kill incel - and they make it seems like CHAD did this to have more sucess on local dating market.
And there would be ten sequels. Second film would be good, third one is box office flop, and then we have straight to dvd sequels.
