This movie is probably most famous for celebrity skin in the form of a young and topless Deborah Winger, but frankly that's the least interesting thing about it. This is another warped and completely irresponsible movie about slutty 70's teenage girls (including such luminaries of the "genre" as Janet Woods and Cheryl "Rainbeaux" Smith)except here they're playing (very unconvincingly, I might add) slutty '50's teenage girls. The plot, to use the term loosely, involves five girls at the eponymous slumber party sitting around reminiscing about their "first time". These vignettes are neither funny nor usually even remotely believable, so this movie doesn't really succeed either as a comedy or as a realistic coming-of-age film. It does, however, excel on a level of pure sexploitative trash.
To illustrate, in a scene that even made a 70's sleaze aficionado like myself cringe, one of our randy virgins "loses it" to a middle-aged family friend who catches her reading "Lolita" (great literary allusion that). But then her father catches them and rather than thrashing the guy within an inch of his life like any normal father he dismisses him and instead puts his naked daughter over his knee for a spanking (!) which she apparently enjoys (!!)prompting the other girls to talk about how they too kind of enjoy being spanked by their fathers (!!!). In the movie's defense the actresses are all obviously in their early twenties and not remotely believable as teenagers (or virgins), but STILL you have to wonder what kind of perverts this movie was originally aimed at.
Amazingly, for such a thoroughly disreputable movie, it has an incredible soundtrack of top 50's hits. Not since "The Last American Virgin" have I witnessed such a collision of bad cinematic taste and famous pop music. I don't know what it would say about ME to recommend this thing to anybody, but if this kind of irredeemable sleaze does it for you . . .
