A mental collection of visual images one stores in ones mind to remember later for purposes of 'self pleasure' see: masturbation. Entered into the spank bank are an array of images of people (usually ones you want to bone) in either suggestive or totally non-sexual situations generally seen in real life.

Ie; a girl in a mini skit, a low cut top and/or heels/A girl waiting at a traffic light eating a lollipop. A girl bending over to pick up a coin. A girl at a club making out with another chick.

A guy doing push-ups at the gym. Guys at the office etc...
