What it is:
Yuppie is short for young urban professional.
How it works (Example):
Yuppies are usually in their twenties or thirties, just out of college or graduate school, and have high-paying jobs in the city. They tend to lead affluent lifetstyles.
In modern usage, the term may refer to any person who is obviously affluent or even arrogant.
Why it Matters:
The term was very popular in the 1980s. Though the term used to be aspirational, it has since evolved to be more derogatory.
