In honor of hungry arcade icon Pac-Man‘s 30th birthday, The Digital Vegetarian unearths this photo demonstration of the Sexy Ms. Pac-Man Halloween costume, and how it works (you pull your sexy castle grommet skirt up to reveal a ghost!) I surveyed my fair share of ridiculous sexy Halloween costumes last October, but Sexy Ms. Pacman may be the most curious of them all. Why is the ghost on her vagina? Why is Pacman trying to eat Ms. Pacman—-on some boobs? Shouldn’t the wearer keep her sexy castle grommet skirt on, in order to protect Pacman and his other half from this life-sucking vagina ghost? Whose side is she on, anyway? Whatever. Sexy! [Via Jess at Birthday Bread Horse].
