When Anna Kendrick was asked to pose seductively for a promotional poster of her upcoming film Pitch Perfect 2, she refused, crossing her arms instead. She had no idea that her actions would spark such a big movement.

According to Cosmopolitan, the studio involved with the photo shoot wasn't super happy with Anna for doing it her way. And her powerful, I-don't-care-what-you-think-not-at-all stance hasn't gone unnoticed. Pitch Perfect fans from around the world are now taking pictures of themselves posing in front of the poster in Anna solidarity, creating one of the coolest movements on social media: the #BossPitch movement.

When she noticed what fans were doing in her honor, she posted collages on her Instagram, with the caption: "They were sweating because I wouldn’t strike a sexy pose. Love that you guys embrace Beca the badass."
