The "backpack" is a sexual act in which a male stands behind a female and reaches his arms over her shoulders inserting a finger from each hand into her vagina. After insertion the male then mounts the females back assuming a "piggy back" position. After the male is airborne he continues to "finger blast" the female. *This is usually performed while dancing*
