Not saying any of these are great entertainment, some are fun, but they fit the criteria:
Gutterballs - Nasty ****ing slasher and very ****ing dumb. You'll get ****ing sick of ****ing hearing the ****ing eff word. Half the ****ing script is ****ing eff words.
Hanger - Same director as Gutterballs. This is ****ing bad, looks ****ing terrible and is really ****ing awful. Writer/Director probably wore out the F-U-C and K's on his keyboard writing these two movies.
Dear God No! - Grindhouse wanna be biker/Nazi-sploitation.
Frankenstein Created Bikers (sequel to Dear God No!) - More epic than Dear God No. Looks a lot better. A little long but is more awful than Dear God No
The Night of Something Strange - horror-comedy. First scene is necrophilia. Second is incest/rape. Yeah, real funny stuff.
Run Bitch Run - Rape revenge grindhouse wanna be.
The Manson Family - Title says it all
The Girl Next Door - Probably the most well known of all these movies. Young girl is tortured by her aunt, cousins and neighborhood kids.
Moebius - I only watched it once a while back but it was pretty good. The best movie here but it's kind of hard to explain.
