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?
A very gassy, extended fart when in a confined space and the wind has nowhere to escape, for example when sitting on a chair or under the covers in a bed. It derives from the stacking up of the gases, which the culprit is desperate not to disturb and the subsequent stacking up of guilt as s/he knows it's only a matter of time before s/he's discovered.
A: Somebody stacked. B stop stacking!
B: I didn't. It was C. He stacked under the covers. I felt the whole bed vibrate.
