Overdefense 

Term applying to combat games. When your computer-cotrolled opponent is almost impossible to hurt because they are using defense (or any method to avoid harm) at least 93% of the time. Almost certain to turn a terrific victory into a frustrating (and-if other people are present-humiliating) defeat.

I had a great run in Mortal Kombat until Johnny Cage started using overdefense and cost me everything.

overdefined 

what words become when they've had 100 or 200 definitions on Urbandictionary. Some that have had at least 200 definitions are: fucktard George Bush fuck penis. Some have between 100 and 200 definitions. Those are: ass republican your mom britney spears. There are probably more, but that's all I could think of. I haven't seen any that reached 300 yet!

So many words on Urbandictionary.com are overdefined!
