MacFiend 

Strange creature living somewhere in the woods, he is looking at sic pictures all day. Sometimes he may even attack strangers who are passing by.

Oh man, I got attacked by a MacFiend again.

Mac Fiend  

A specie of human who will compulsively buy any product as long as there is a lower case "i" in front of its name.

my friend is such a Mac Fiend he says things like "hey dude i waited in line for three and a half days to get my new iToaster. I love it even though it cost 580 dollars more than my other one and has the same functionality!!!"

Macfriend 

Someone who appears to be a friend while convincing you to buy an Apple Mac. Once you buy a Mac and find out for yourself how unreliable it is, your friend is nowhere to be found.

I used to think Brad was a friend but now that I'm having trouble with my new Mac he is nowhere to be found. I should have known he was just a Macfriend.

McFiend 

A person who cannot control their cravings for Mcdonalds after 12 AM.

We have to hit McDonalds on the way home because Evan is a McFiend.
