facebook memory 

The act of using Facebook to recall a previous night's intoxicated events using photos added by others.

I don't remember going to that bar at all. I only have a facebook memory thanks to Adams photos.

Facebook Memory Lapse 

The instance when one takes a "couple secs" to check his/ her facebook before starting homework, spends an hour checking, then forgets entirely what they were doing the moments before checking facebook

Girl: Hey did you get the annotations for English done last night?
Guy: Shit, I must've had facebook memory lapse, I totally forgot!
Girl: Dipshit
