Pad Launching 

1. When a girl starts her period.

2. When Apple starts selling an awesome new version of the iPad.

Katy: I'm not too excited about the next four days, pad launching is tomorrow.
Matt: Oh... I'm sorry... I can't imagine how that must feel... do you get bad cramps or something?
Katy: Umm... we'll just be pretty busy at the Apple Store all weekend.
*awkward silence*
Matt: Wait, did you say "pad launching?"
Katy: Yeah, the new iPad 2 goes on sale tomorrow.
Matt: *facepalm*

Saint Peter's Launching Pad 

Beds in a hospital ward, usually in the emergency department, that are reserved for the sickest patients who are not expected to get better.
Named this because Saint Peter is said to guard the gates of heaven and the people on these beds are presumed to be seeing him very soon.

Three patients on Saint Peter's launching pad.
