microsleep 

The kind of involuntary sleep you experience when you're really tired and trying to stay awake in a monotonous situation, like a class lecture. One minute you're propping your head in your hand, trying to pay attention, when all of a sudden you're out -- at least until your elbow slips sideways or your head falls forward, jarring you back to attention. Caused by a consistent lack of sleep over several days. Often the cause of car accidents, when the driver nods off during long hauls.

Man, I had a really bad microsleep during trig yesterday. I couldn't stay awake for more than a minute or two.

microsleep 

Usually results from sleep deprivation. Microsleep may be linked to narcolepsy and other sleep disorders such as severe insomnia. The person may believe they are awake but are actually in the REM cycle of the sleep process. It happens so quick that the person may not even be aware that they are sleeping. Episodes can last from 30 seconds to a few minutes. Usually, the person enters the dream state and may slip in and out of the REM cycle periodically.

I just fell asleep for 30 seconds, I just had a microsleep episode.

microsleep

Sleeping for a small period of time to increase awareness, often because you have a task you need to complete that conflicts with your sleep schedule. Coined by Swedish Twitch streamer Vargskelethor Joel, who used the term to describe sleeping in SETI simulator Voices of the Void.

Microsheep 

(n) 1. A person, or group of people, that buy a Microsoft product after being influenced by hype. 2. A person, or group of people, that buy a Microsoft product without first doing some research on the product they are about to buy.

1) My friend bought a suXbox 360 just to have downloadable content, but now that Microsheep is paying to use his own bandwidth to play games online and cannot watch high-definition movies.

2) Mostly everyone I know kept Windows XP but there are still a few Microsheep that insist on its dumbed-down incompatible version, Windows Vista, to be the best operating system.
