{{{
Lame delegation:  "A lame delegations exists [sic] when a nameserver
      is delegated responsibility for providing nameservice for a zone
      (via NS records) but is not performing nameservice for that zone
      (usually because it is not set up as a primary or secondary for
      the zone)."  (Quoted from [RFC1912], Section 2.8) 

Another definition is that a lame delegation "...happens when a name
      server is listed in the NS records for some domain and in fact it
      is not a server for that domain. 
}}}

{{{
Queries are thus sent to the wrong servers, who don't know nothing [sic] (at least not as
      expected) about the queried domain.  Furthermore, sometimes these
      hosts (if they exist!) don't even run name servers."  (Quoted from
      [RFC1713], Section 2.3)
