Need more proof that Oprah Winfrey has had an indelible impact on pop culture? Just open up your dictionary.

For its 2012 edition, the folks at Merriam-Webster have announced they're adding the media empress' ubiquitous "aha moment" to their dictionary, defining it as "a moment of sudden realization, inspiration, insight, recognition, or comprehension."

"I always love those moments when I sit down to talk to somebody and they say something that makes me look at life or a situation in a completely different way," Winfrey explains in a video posted on Merriam-Webster's site. "And I say, 'Aha! I get it!' Light bulb . . . and the little hairs on your arm stand up. That is an aha moment."

Other terms being included this year? Sexting, energy drink, f-bomb, man cave and bucket list.

No word yet on if Winfrey's mug will appear alongside the definition of her beloved phrase.
