In the year that I was born, 1966, some words which were used for the first time in print were:
cryonics, art deco, assault weapon, ROM, biocontainment, hot button, kung fu, meth, male-pattern baldness, multitasking, multiorgasmic, Medicaid, number cruncher, paperless, street smarts, ranch dressing, z-score
I would have guessed that many of these terms were older.
New words in recent years are ico, manspreading, utility token and aquafaba (?).
All this is according to the Merriam-Webster Time Traveler.
