I am usually a veritable encyclopedia of 80s movies, but I have this one very vague memory of a movie that I THOUGHT was either "Saturday the 14th" or "Trasylvania 6-5000" but it isn't. Although I recall it being in a similar vein as those films.
What I remember is:
Two guys driving somewhere in a car, one guy tells the other that he lost his viriginity to his step mother out of pity when he was feeling depressed.
One of the guys has a large mole on his arm that eventually turns into a monster(?)
THere is a teddy bear that, at one point when someone falls asleep on a bed, comes to life and a tiny blade emerges from its paw.
