An Apple fanboy; A member of the Mac trend, especially one who purchases Apple hardware to be fashionable and not because of any virtue of the hardware over PC hardware.
A very common bunch of douchebags im sure you've seen. These iTools can be easily spotted having their iPod headphones in there ears at all times, even when they aren't listening to there iPod.
Bob: Steve, what you listening to?
Steve: Oh, nothing.
Bob: Goddamit! Take those headphones out of your ears! Your such an iTool!
A person who buys everything from Apple (iPod, iPad, MacBook, etc) even though they might not like or want it...they just want to be part of the "Apple" crowd and submit to doing so like a bot...
"Jose is dreaming about the iPad mini--Gosh, he's such an iTool"
An annoying Mac user who is in love with Steve Jobs and Apple and constantly has to remind you that any issue you are currently having with your PC/Music Player/Dishwasher could be easily resolved if you just switched to Apple.
"Hexx0r_jobs is such an iTroll, every time I come onto the forum to ask a question about my PC, he tells me I can resolve the issue by getting a Mac. What an asshole!"
An overzealous person who is willing to pay top dollar for an Apple product as soon as it becomes available. They have been known to stand in line for hours, even camp out at a retail store, to try to be the first person to buy a newly-released Apple product.
Leaira: Hey, Jordan, look at all those people lining up by the door! What's going on?
Jordan: Oh, the new iPhone is coming out at midnight tonight. They want to be the first people to get one.
Leaira: Hahaha! That's crazy! Don't they know these things will be obsolete in like 6 months and they'll come out with something else?
Jordan: I'm sure some do, but I guess they want to be able to brag that they have one. What a bunch of iFools!
Leaira: Yeah, no doubt! In a year they won't even be able to give these things away on eBay!
