dord 

n. Physics & Chem. Density. A non-existant or ghost-word originating from mistakes in Webster's New International Dictionary editions 1934-1939. Original entry should have been "D or d" in the abbrevations section, when something messed up.

no example, as the word does not exist

Dord 

Added to the Merriam-Webster dictionary incorrectly, its original definition is:

1. D or d (n): Abbreviation for "Density".
This was however entered incorrectly as "Dord", giving it this definition.

If you wanted to use it in the context of an adjective, it can mean...
2. Dord (adj): Alternate word for "Dense".

Due to this mistake it can however take on another meaning.

3. Dord (n): A word that is incorrectly used or does not technically exist either through intention or misconception.

"Dord" itself falls into this description, and so does pretty much everything else on Urban Dictionary.
This can be imagined as an abbreviation for "Denied word", as a mnemonic device though that is not its origin.

1. The loaf of bread has a very low dord.

2. Wow, this giant TV is pretty darn dord.

3. Urban Dictionary is not a place to learn, it's just a load of dords.

dord 

the best word in the history of the English language. this word should be put back in the dictionary and should encompass not only density in the scientific sense but should also be used to describe a dumb person.

Dord 

The multi-Asian cretin that lurks only in the early hours of the day, when no one expects in the catacombs deep in the earth. It is said by many victims that this weird creature hungers of young female dwarfs in the slums of japan, preying and capturing them demanding a ransom of their toenails which is said that toenails make him more horny than Kevin spacey havin a nosh or he will proceed to peg them non-stop until dawn. Many victims also claim that the wild dord also makes a bizarre and eerie noise, growling that sounds like a mix of a cough and sneeze, which is easy to catch when heard. He also crawls on all 4s on the ground rapidly with its torso facing upwards chasing its next victim.

BEWARE OF THE DORD!!!
