cougar lift
n. Cosmetic surgery performed on a middle-aged woman to enhance her prospects of dating younger men.
The 'Cougar' euphemism generally refers to older women who date or marry younger men. Many surgeons and elective surgery centers have coined the "Cougar Lift" term to identify an entire category of cosmetic procedures for women in this demographic who are engaged in new romantic relationships — and want to look as vibrant and youthful as they feel.
The number of women age 45 and over choosing to have breast enhancements has doubled. Procedures popular among cougars include facial fillers and buttock implants. Leading the 'Cougar Lifts' trend are stars like Demi Moore, Kylie and Madonna.
