When I was a kid I read a young adult novel about a gang of girls who wear white lipstick and back comb their hair. They have sort of a girl gang, and they put each other through initiations. One of them is to bring back a used condom as proof of a conquest and in order to cheat, one girl makes a semen recipe in the kitchen. When she gives it to the ringleader and said it belonged to a particular boy, the ringleader says something dumb and grabs it and guzzles it. It was really strange, but I’m pretty sure it was a novel for young people. I would have read it in the early eighties. I think it was supposed to be set in the 60s. Does that ring a bell for anyone?
