Cryptic posts in facebook that express a vague sentiment but do not provide any details, clearly designed to bait friends to ask follow-up questions.
A facebookwall post that could be considered facebait would be posts like "Today is the day!" or "Ugh, I am over it..." or "Now I know why I should stay home..." or "Hurt and disappointed..."
The sabotaging of one's facebook, most notably the status. This is usually done when your facebook is left unnaccounted for and there are friends or roomates around.
My status read "Eddie enjoys dick" after my friend faceabotaged my facebook.
"Jim is snorting coke off of a hooker's ass" was the product of my latest faceabotage.
When you postsomething on facebook that is crude or potentially offensive, and then immediately delete it after you realize that all of your family members are going to see it.
Man I heard this hilarious joke about taking a dump on an old lady's chest, and I posted it on facebook, but then I remembered that I'm friends with my grandma. I totally facebalked!
A mysterious or cryptic post on Facebook that is either only understood by a very small group of people or is complete non-sense. The proper facebaffle is never explained no matter if others inquire or not.
Suzy facebaffled when she posted “Last night I saw…WOW!” on Facebook then never explained what she meant.
