When:
Lookups spiked on January 19, 2012.
Why:
Celebrity chef Paula Deen, famous for high-calorie comfort food, announced that she has Type 2 diabetes.
Many news reports used egregious ("conspicuously bad" or "flagrant") in describing some of her culinary creations - like a hamburger with bacon and fried egg served on doughnuts for rolls.
Egregious comes from the Greek words that mean "apart from the herd" and in English is used for things that are outside of normal or acceptable standards or behavior.
