shambler

The fucked up monster that scared the crap out of you in Quake 1.

A foreign entity with a human disguise that is less than convincing.

1. One who is usually quiet but can become enraged in seconds.
2. One who cannot construct well-thoughout arguments and thus, must result on the use of force.
3. A man who shambles at the sight of one greater.
4. A woman who reacts wildly in bed.
5. One disloyal to the British Monarchy and found guilty of High Treason under the High Courts of the Dominion of New England.

Compulsive Shambling, or more colloquially, "C Sham", occurs when an individual is repeatedly deprived of sleep and/or stimulation and proceeds to move around at an incredibly slow and awkward pace with an often fatigued or expressionless face akin to a zombie. The few words they try to speak are usually no more understandable than a loud mumble. Compulsive Shamblers or "Shams" are often spotted at the workplace or at school and generally accomplish no more than amusing those individuals who are equally on the border of CS (Compulsive Shamblification).

A predatory nightmare summoned from the darkest recesses of the unknown.
