An office phenomenon in which a colleague, tired from boredom, sleep deprivation, or partying, is fighting the urge to fall asleep in a multi hour review meeting. The eyes shut for brief seconds and then half open as the victim is hanging on to the last thread of alertness.
After hour two of the weekly operations review meeting, Ed was observed going into screen saver mode. His colleagues enjoyed watching his battle with consciousness.

A piece of software, usually something lame that was installed by default with your OS, that takes over when your PC thinks you're not using it any more.
Some screensavers are cute, like Viking Kittens, and some have a purpose, like Make Love Not Spam, but most are just unimaginative lameness that installed by default with sWindles.
