The case where someone can't stop themselves from posting every insignificant thought or occurrence to their Facebook status. Similar to diarrhea of the mouth but for social networks.
Joe: Damn, Jill changes her Facebook status like every 5 minutes!

Mary: I know, That skank has Facebook diarrhea.

When someone will not stop posting facebook posts, no matter how many people dont care
"Jim has got a bad case of facebook diarrhea. He will not posting posts"

"I know. Does he actually think people care about him?"
