smackbook

Facebook, the most addictive website in the world. Also 'crackbook.' In some circumstances, smackbook may be more appropriate to say than crackbook.

Yesterday I spent 14 hours on smackbook, which now rivals only my heroine addiction in competition for my free time.

"Hey man, I saw your girlfriend dumped you on crackbook! You are one pathetic loser!"
"Seriously, I am so done with this smackbook."

smackbooking

Any of several forms of jest, put-down, or smack talking about or between people on Facebook, where the parties appear to be verbally feuding.

John and Jason engaged in a playful bout of smackbooking on their Facebook walls when Jason claimed his car was faster than John's.
