Someone who gives the impression of placing material things above people.
However, this is usually used by people who feel inferior to someone who has nicer clothes, better shoes, etc. than themself. So they use this word to try to lift themselves out of their dark, sad hole.
Ashley: Wow, I really love those shoes Jen's wearing... & Her shirt is really cute too.
Amanda: Pshh, she's so materialistic. At least I have.. Friends...
What everyone IS, no matter how hard they claim material things do not matter to them. THIS coming from an asshat with $80 trendy-ass jeans complete with all those useless pockets, zippers and straps and $300 worth of "alternative" jewelery.
"Um... don't need to get me anything this Christmas. I'm kind of like the non-materialistic type. Really, I am."
-that trendily-clad person that pissed me off with the same old non-materialistic bullshit.
Sister: This meeting was to discuss the rough draft of my essay, where we discussed the subsidiary questions I added in my rough draft. We also discussed the relationship between my main title and the real-life situations I chose to use in my essay. We discussed the structure of my essay as well, specifically the Math AOK section and how it relates to the contradiction of the title. This second meeting was particularly helpful in discussing the implications of my essay claims and how to apply the title across various areas of knowledge. There were many sections of the essay that could have been cut down in wordiness and the ways of knowing required further and more in-depth analysis.
