Lady cupboard

Euphemism for a vagina. No idea how my esteemed work colleague came up with this term. Had us in stitches. Especially as it followed on from an incident involving a 'sprung bristley flap' which is apparently a modern post box but sounds like a viscous lady garden.

I am feeling frisky, I need you to clean out my lady cupboard with your gorgeous tongue.

old lady's cupboards

When something literally has the smell or taste of an old lady's cupboards. It is not an euphemism.

-An old lady once gave me a KitKat chocolate brar that she had in her cupboard for 5 years, and it literally tasted like old lady's cupboards.
-Is old lady's cupboards some kind of euphemism?
(laughter and hilarity all around)
-No, it is not.
