An Applewhore is somebody who buys every new Mac product, and talks about it all the time. If you even mention the word "PC", they look like the might vomit. They are constantly on their iPhones, and bought the iPad as soon as it came out. Even if they weren't quite sure what was so great about it, they tell everyone that "It's the best product ever!"
Person 1: Wow, check out Maggie, she's such an Applewhore.
Person 2: What do you mean?
Person 1: Just look at her, iPhone in one hand, iPad in the other, with her laptop bag over her shoulder.
Person 2: Whoa, totally.
Maggie: OMGZ U GUYZ THEY'RE MAKING A NEW IPHONE FROM BAMBOO AND IT'S COMPLETELY ECO FRIENDLY WOOOO. Technology is so awesome.
