An editor who uses more than just rules to judge what goes into their system. Usually they use their personal opinions as a good portion of the descrimination process. An extreme loose editor may be know as an editing vigilante.
An editor that doesn't care at all about the site or what definitons get through, so they publish/delete any definition in front of them without bothering to read them. You'll be lucky to get the good kind who will publish your definition on a whim.
I, a loose editor, sat there for about three minutes publishing pages of definitons before i got bored.
