(n.) Used to stand for Young Urban Professionals, but has now strayed to define the 20-year-olds at Starbucks
who type for hours on their laptops, probably writing a novel that they apparently want EVERYONE at Starbucks to be interested in. They often wear stylish black glasses, slim black clothing, tote yoga mats, and big bulky colored scarves regardless of the temperature outside. They are health conscious, live off salad and black coffee, and often frequent poetry slams and wear jaunty berets. If you ask them what they are writing about, expect to be either talked down to, or have them use the biggest words they can think of, even if they're out of context, hoping you don't know the meaning anyway.
Mitch: "Hey look, I've always wondered what it is those yuppies type away on."
Frank: "Bad idea man."
Mitch: "S'cuse me miss, can I ask what you're writing?"
Yuppie: (Looks up from coffee as if she's never seen people before) "It's an esoteric collectivist's detailed analysis of the resurgence of middle-American culture in relation to the increase in demand for soy milk since its invention in-"
Frank and Mitch have died.
(adj.) When someone is one way in person, and a COMPLETELY DIFFERENT person online (on Facebook, in texts, IM, etc.), so much so that you wouldn't recognize them. The actual word has its roots in bi-polar and the way Apple puts a lowercase i in front of all their capitalized product names.
