The nicest, funniest, most genuine girl ever. She is beautiful and is 1/1,000,000,000 and if you're lucky enough to find an Audnia she's a definite keeper, even if she lives far away. She may go by Audi, and if she does, shes definitely had to deal with a ton of car jokes.

Briefly, "the realization that each random passerby is living a life as vivid and complex as your own." Originally from the Dictionary of Obscure Sorrows, which has a lot more beautiful neologism definitions like this you might enjoy.
