A portmanteau of the words Definition and Defamation.
This is the act of going to the trouble of inaccurately defining a word on
Urbandictionary just to make a private
joke at the expense of a member of your extended social circle, who, since you'll have to go to the trouble of dragging them to a computer, telling them the Urbandictiony url to type in, and then telling them which is the one word out of thousands that personally mentions the name of the person to
get any kind of reaction out of them, thus negating the possible humour from the act of the
joke, (since this is like having to stop and explain a
joke after telling it), and thereby confusing the issue for everyone else in the world who is obviously not either you and your two sniggering sychopantic hanger-ons who think this kind of thing is even remotely interesting or clever.
