look up any word, like the eiffel tower:
Abbreviation for Facebook Freakout
When you are on facebook and it is overloaded, and you lose connection, leaving anyone you are chatting with to believe you actually did just go offline.
Sorry, just had a major FBFO. I'm back.

Facebooking from the office. The opposite of facebooking from home.
"Hey Mandy, I saw your comments on Facebook earlier, did you stay home today?"

"Nah, I was fbfo."

"Ah, gotcha."
