I sometimes contemplate asking about this one when a movie ID question comes up. I saw part of it a few years back on MeTV or similar. Filmed probably in the 1980s, set earlier. Pair of early teen girls. Takes place in a city. Possibly a scene in a train or subway. One of the actresses, IIRC, went on to some minor but mostly past fame, but I forgot who it was. The one moment I really remember is the two girls lying outside talking and one mentioning how she wanted to meet some handsome man who wiuld take her and ravish her, and I thought about how “ravish” means “rape” and it isn’t likely a modern movie would contain a line like that.
(And now I’m waiting for most of the thread to be an irrelevant tangent on the definition of “ravish”.)
The World of Henry Orient by chance ? Peter Sellers plays the title character, but the story is really about the 2 pre-teen girls who become obsessed (stalk) with him. But it’s a bit older than 80’s.
For the “feel” of the movie and the age of the actresses, a while back someone mentioned Little Darlings with Tatum O’Neil in a thread and that sounded close enough that it might be it, but it wasn’t.
