A measure of good or bad based on a sliding scale called the "Delkus Index". The Delkus Index works much like a golf score in that the lower the score, the more desirable the thing being measured. The D-Index measures from a +10 (highly undesirable) to a -10 (highly desirable). The rare "zero-Delkus" score occurs when a situation is equally good and bad. Named after Pete Delkus, a local meteorologist who had a promising career as a minor league pitcher but now spends time miscalculating the weather for a Dallas news channel.

"Mad Delkus, bro. Bad acting, bad special effects and too much chick-flick crap. I might hit that with a +8 on the D-I."
