K-rad literally means 1000 times rad, just as a kbyte or kilobyte refers to around 1000 bytes.

K-rad was made popular in the 1980s by computer hacker circles. The word 'rad' reffered to a radical act performed by a hacker which deserved congratulations.

The term k-rad originated around the same time people started talking in numbers l1k3 th15. This type of language first started apearing on BBSes and FTP warez sites.

(Kilo Rad) or (cool X 1000)

Derived from Kilo (1000) * rad (see radical - meaning cool or amazing)

In keeping with computer terminology, its use was popular on dialup bulletin board systems (BBSes) in the 80s and early 90s, frequented by first and second generation hackers and computer enthusiasts.

Psychotic blonde alter-ego of Hiwatari Satoshi (of the manga D.N. Angel). He may be pure evil, but he's pretty damn hot for a psychopath.
Krad is a Satoshi-molester.

From the skater and phreaker slang "okay rad" (rad was short form of 'radical') commonly shortened to "kay rad". Was shortened to "krad" in text communications, possibly spawned "kthx".
