Because you exclaim, "Lovely Jubbly!" every time you score a great parking space; because you describe the girl who lives next door as "bootylicious;" because you consider yourself a "cyberslacker"...the Oxford dictionary has heard your calls, and all these words (and many others including Bada Bing, Muggle, SARS, and Boy Band) have been inducted into the dictionary. The dictionary's publishers say words are only included if they are well-known and have proven they can pass the test of time. Yeah, okay, but Lovely Jubbly?!
