Stupid Facebook. Used to express frustration with Facebook for numerous reasons.

As it is described by its Facebook fan page:
It's not just Facebook. It's stupid Facebook. It's often broken, usually annoying, and occasionally appreciated. But stupid. sFB.
"Facebook is messed up again. sFB."

More often "sFB." appears to express user frustration with no other explanation needed.
