How one might refer to facebook if out of their hundreds of facebook friends they are unable to name 10 offhand. It derives from the friends seemingly having been copied and pasted off other people's profiles.
A: How many friends have I got now on paste-book?
(A logs on)
A: Yippee, I've got 1000 now 30 accepted in the middle of the night.
(A Logs off)
B: Aren't you going to have a look at their profiles?
