Anyone who's so ignorant of traffic that they tell someone "you can't come in here" when they're having one of their stupid little block parties.
In my opinion, yuppie neighborhoods are no better than the ghetto.
Yuppies tend to have at least Bachelors degrees (but more common, these days, graduate or professional degrees such as JD's and MBA's) and work in high paying professions such as Law, Accounting, Investment Banking, Engineering etc. Yuppies are known for their conspicous level of consumption and obsession with status symbols.
They tend to reside in urban environs such as Manhattan or San Francisco, but there are also suburban areas that are heavily populated with yuppies (such as Menlo Park/Palo Alto and Marin County, all in northern California).
Often times, Yuppies are "Big Hat, No Cattle" types who pay $2,000 a month to rent a swanky apartment and spend another $1,000 a month financing a luxury car, but at the end of the day have a negative networth because they are so in debt from their student loans and credit card bills.
For a perfect example of the yuppie lifestyle, watch the movie American Psycho.
Landlord: Because the yuppies are willing to pay top dollar for the prestigous address and the fact that the building is right down the street from all the swanky restaurants, nightclubs, clothing boutiques and cafes.
I live in a yupped out town.
Rich guys that buy harleys that think they're bikers.
Yuppies (or: YUPS) are in the age group of 22-32, live in large, expensive subdivisions, and live with general technology and wealth. Yuppies commonly drive foreign luxury cars as well as small SUVs, such as a Honda CR-V, Toyota Rav-4, or Jeep Liberty. Yuppies are often seen at nature centers, walking trails, or beach-side campgrounds. Yuppies often pay $300,000 for houses with an extremely small yard and no foliage.
Yuppies get along easily with other yuppies. However, anyone "below" them on the social chain they will not talk to.
Yuppies may be male or female, however, when a female yuppie becomes pregnant and has a child, she then becomes a soccer mom.
