According to the ARRL web site:
General or Technician class licensees can seek a 1x3 call sign (beginning with prefix N, K or W),
or 2x3 call sign (beginning with prefix letter K or W) -- FCC call sign Groups C or D.http://www.arrl.org/vanity-call-signs
So.... Yeah.... A 2x3 Group D call is standard issue for both Techs and Generals and begins with K or W. Group C calls are 1x3 and begin with K, N or W.
You might want to mention to your friend that NØSEX is already assigned to Marvin Rice of Iron, MN who is also a Tech.
