For folks who are confused by this: SWPL is the acronym for Stuff White People Like, which is a blog. It basically described (by means of caricature) an emerging social class in America of urban, socially liberal, upper middle class professionals. Kinda like "yuppie" but with acid tests more appropriate to 2012.

"SWPL" has subsequently been appropriated to describe that social class by commentators on the Internet. It's not a perfect map to the territory but fits it closely enough to have significant predictive power.
