#1. Cougar

An older woman who romantically pursues younger men. Example: Demi Moore, 45, snagging hubby Ashton Kutcher, 29. Although an offensive term to some, others consider it a positive sign of society's increasing acceptance of older women's sex appeal. This summer's reality show Age of Love went so far as to pit a team of Cougars, in or near their 40s, against a team of Kittens, all in their 20s, in a competition for the affections of a hunky 30-year-old. (Alas, a Kitten won.)
