Using a toothpick, skewer the marshmallow and chocolate piece together. Set aside.
Place the crushed graham crackers onto a saucer or small plate. Rim a martini glass with the orange segment, and then dip the rim of the glass into the graham crackers to coat. Drizzle the chocolate sauce onto the sides of the glass. Set aside.
Combine the vodka and chocolate liqueur in a cocktail shaker filled with ice and shake. Light the marshmallow on fire and place into the martini glass. Pour the cocktail over top to extinguish the marshmallow and serve.
