k-

( pref.)

   [rare;  poss  fr.  kilo-  prefix]  Extremely. Rare among hackers, but
   quite  common  among  crackers and {warez d00dz} in compounds such as
   k-kool  /K´kool´/, k-rad /K´rad´/, and k-awesome /K´aw`sm/. Also used
   to   intensify   negatives;  thus,  k-evil,  k-lame,  k-screwed,  and
   k-annoying.  Overuse  of  this  prefix,  or  use  in  more  formal or
   technical contexts, is considered an indicator of {lamer} status.
