But if you thought slang for a sexy and physically attractive person, well, ding, ding. That's because dictionary.com added over 300 new words and definitions. The website is based on the Random House Webster's Unabridged Dictionary. And some of the new words are drawn from meme culture. So add in oof and yeet. It's MORNING EDITION.
