Oh, and 'big white wedding' isn't really a slang, they're just alluding to a large traditional wedding. And I think the reason it's news is that it's strange to see these people who usually live rather hand to mouth throwing such a huge extravagant event. Along the same lines as the not paying taxes and/or stealing thing, they tend to be somewhat anarchistic, which usually includes anti- commercial type things- ie, they tend to barter instead of shell out whopping amounts on (tasteless) wedding dresses.
