1. A dessert
pie with filling made from soft
cheese such as ricotta, Philadelphia or farmer's
cheese. Commonly lemon or vanilla flavored, baked without top crust and often topped with fruit. (Technically a
pie, not a cake, since it is unleavened and contains little or no flour)
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.
