San Diego Sandal
Similar to a Mississippi Handbag, a sexual practice that involves the female (or gay 'bottom') placing the toes of their feet into the anus of the recipient. Maximum sexual arousal is achieved through a fast and intense "wiggle your big toe (ie Kill Bill)" motion or if the person who is administering the act has a hangnail and/or an erotic "Butt Bunions."
That bitch was too busy rolling a joint to give me a Mississippi Handbag, so she gave me a San Diego Sandal instead.
