Being a woman is, largely, about performance - how we dress and modify our bodies, what we say, the roles we play, and how we conform to expectations. Gender stereotypes are still deeply embedded in our society, but Emer O'Toole is on a mission to re-write the old script and bend the rules of gender - and she shows how and why we should all be joining in. Exploring what it means to 'act like a girl', Emer takes us on a hilarious and thought-provoking journey through her life (including singing 'Get Your Pits Out for the Lads' on national TV after growing out her body hair). Cross-dressing, booty-shaking, sexual disasters, family dinners and full-body waxing are all lovingly dissected in search of wisdom. With game-changing ideas, academic intelligence and laugh-out-loud humour, this book will open your mind and revolutionise the way that you think about gender.
