poser

( n.)

   [from  French  poseur] A {wannabee}; not hacker slang, but used among
   crackers,  phreaks  and  {warez d00dz}. Not as negative as {lamer} or
   {leech}. Probably derives from a similar usage among punk-rockers and
   metalheads,  putting down those who "talk the talk but don't walk the
   walk".
