2. A genre of glamour photography and poster art made popular in wartime pin-ups of the 1940's, often featuring modest poses by movie starlets displaying lots of leg but little explicit nudity. So called because of the resemblance of a stocking-clad female thigh to the layers of a cheesecake dessert.
3. (Hence) Any pictures, modeling, posing or shooting for glamour photography or softcore porn.
4. (From above) Anything that is soft, sweet and enjoyable.
Thanks for telling me about this cheesecake job opportunity.
Oh, I am eating cheesecake.
Cheesecake is one of the best desserts in life.
