Used to mean two very different things, either: (a) an on-hold domain or (b) an available domain.
a domain where the last owner has let the registration expire.

Some webmasters will try to use this trick as a way to get legitimate links and referral traffic to sites containing adult content.
a name that passed the expiration date and started the deletion process
