The name used to describe the condition where someone is severely deprived of sleep, see also: lack of sleep.

A condition suffered by only the poorest of souls, especially those with young siblings who can't seem to use the printer without your assistance.

May be the result of insomnia, or an addiction to noding.

Treatment may be one of the following:

- Sleeping pills of some sort, which force you into a state of unconciousness.
- Being hit over the head with a large club, which will also force you into a state of unconciousness.
- Ear plugs, they make the world a better place.
