Spankbank 

Is the mental image bank that thirsty men store as a visual stimuli to later pleasure themselves. However much of these images are gather in creepy inappropriate behavior such as getting to close, putting their crotch right in front of an unsuspecting girl’s face and or groping her during otherwise casual interaction like at work.

My ex roommate, would make small talk w/ me just before he took his shower. I didn’t realize he was filling his spankbank so he could go jerk off until a year later.
