The female version of the ‘wankbank’. A mental storing of things that turn a woman on for later recollection and inevitable masturbation. ‘Bean’ meaning ‘clitoris’, and ‘bank’ meaning storage.
Girl 1: Sup girl, you seen the tight man ass over there?
Girl 2: Mmhmm, damn tight. That’s some might fine ass right there.
Girl 1: Let me scoop some of that up for later, imma add this to the beanbank.
A clumsy oaf whose finger banging skills consist of smashing the clitoris like a polar bear attempting to open a safe full of baby seals.
Her latest suitor spent last evening fumbling around her hatchet wound like the most basic beanbanger for the last time, and left her orgasm unrealized.
