The most annoying and useless people on the Earth.
While many groups of people such as nerds
try to change the world for the better through activism and technology, preps spend nine tenths of their time looking down upon others, using their typically upper class parents to buy them things which make others envious.
However, don't worry about them too much; since they tend to drink heavily and go to shitty colleges, many preps find themselves unable to function in society and end up working for their parents, who are generally lawyers or self employed salespeople. Their more worthy parents wind up hating them and they take up jobs at IHOP or Walmart and get old and hideous
Their idols are generally as shallow as they are, and include any boy band they can find, and typically STD infested sluts like Hannah Montana and Miley Ray Cyrus.
Young preps tend to watch High School Musical; older preps can't afford a TV.
They tend to be Republicans, and pretend to be devout Christians, while drinking more than the average Irish Catholic minister.
