Naco
Trashy. low-class; nouveau riche; tourist Originally a Mexican word used to insult low-class people it's slowly becoming part of the American vernacular because they don't have a word as all-encompassing. It's used as a general insult for someone who you think is less sophisticated than you, regardless of wealth.
Look at all the nacos in Times Square wearing Hard Rock Cafe t-shirts! Maria-Lupe is such a naca. She only eats lobster when she goes out on a date because she thinks it makes her look classy.
