The kids? The children? They think genitalia is edgy and impolite, so take that society. Their friends laugh at them when they're standing by and they bond over how deeply disobedient and hilarious they are, and also how fresh and innovative. And about cishet boys specifically, spoiler alert, but they're really obsessed with penises and if you're among them and you casually point that out while they're being extremely homophobic they will become inconsolably angry and possibly hit you.
