Mayor Walsh has proclaimed today Riot Grrrl Day, an official holiday celebrating the feminist musical movement begun by Kathleen Hanna of Bikini Kill in the early 1990s. Sure, Hanna will be at the Wilbur Theater tonight to show you what Riot Grrrls are made of, but why not let this man explain it to you instead?

Don’t worry, guys, he totally gets it. We give you, “Riot Grrrl Day: Man-splained.”
