The late-2011 update to Facebook, as a combination of the previous Facebook design with a Twitter-like approach. Facebook+Twitter=Facitter. Pronounced like "face sitter" (as in FAY-sitter or FAYS-itter, as per local dialect).
"Good lord, I can't believe how much crap's spraying out of Facitter today," you say to your friend. "People really hate this."
Your friend leans in from behind and closes your open browser window. "Then take it off your face," she says, shaking her head in mild confusion.
