2.
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.

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.
