k-rad 

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.

K-rad 

A failed attempt at doing something rad.

The K comes from the symbol used for a strike against a batter in baseball.

Also used to mean something very rad, with the K coming from the abbreviation for thousand (a thousand times rad).

The disparity between the two meanings is similar to that of "bad" meaning both good and actually bad.

Originates from BBS days, with overuse leading to confusion and hence the split definition. Only should be used on-line. Meaning should be clear from context.

That was so k-rad, you lamer.
