It's appropriately titled, “Dirty Girls.”
The video description from YouTube says:
Shot in 1996 and edited in 2000, this is a short documentary about a group of 13-year-old riot grrrls who were socially ostracized at school by their peers and upperclassmen. Everyone in the schoolyard held strong opinions about these so-called "dirty girls," and meanwhile the "dirty girls" themselves aimed to get their message across by distributing their zine across campus. Directed by Michael Lucid. Music: "Batmobile" by Liz Phair.
