Punk rockers and the F-word: They go together, as a very different sort of musician might have said, like love and marriage, or a horse and carriage. That’s clearly evidenced in this documentary, in which the salty word is sprinkled throughout conversations like, well, liberal doses of salt. But what about, as the title has it, “The Other F Word”? No, you don’t normally think of “fatherhood” when you see the heavily tattooed and pierced men behind the bands that sing (if that’s the right word) songs about giving the powerful the finger. But punks are people, too, and the destiny of most people is to propagate. That unlikely image — of boys who have railed against authority turning into men who have it — is explored in Andrea Blaugrund Nevins’ entertaining, even eye-opening doc.

” ‘Having a baby changed everything.’ You hear that, you hear that. And it totally did,” marvels Jim Lindberg, longtime frontman of Pennywise, one of those bands the average person hasn’t heard of, but which has proven influential to many bands he has. Lindberg is one enthusiastic father: He even wrote a book titled “Punk Rock Dad.” But that doesn’t mean he’s lost his edge. He’s still a hardworking musician, but one who also works hard to fit in family time in between the tours and stints in the studio.
