A computer feature that many people do not use, which allows the computer to to shut down while playing music, games videos, browsing, and running antivirus scans all at the same time. When the computer turns on again, all tasks resume at where they were as if nothing happened.

Despite how awesome that is, most people still close down all their programs and shut down, only to have to start them up again when rebooting.

The idea behind it is simple. Take pretty much everything on the RAM and copy it to C:\hiberfil.sys, which is read again when the system resumes.
Fred was Photoshopping, video editing, chatting, browsing, playing Crysis, writing music, and working in 3D Studio Max on his laptop, but he had to pack up and go to work so he simply saved all his work and hibernated the system.

Get a Hibernate mug for your dad Paul.
When your laptop decides to turn off because it's "battery is low." Usually followed by a yell, a scream, or some profanity.
Haha, this video is hilarious! What, laptop, you're hibernating?! AAARGH! Shit, damn!

Get a hibernating mug for your friend Rihanna.
To disappear off the radar socially. Usually this happens after extended period of partying so a downtime is required to recover.
"Have you seen Maria lately? I haven't heard from her since that party two weeks ago."

"No, I haven't. She must have gone into hibernation."
