I think the attempt to define it really defeats the purpose of it, because while it is giving a number and a list of definitions, it also is saying “but is not limited to”. In other words, the list could go on and on, when in reality you're talking about a word that is very difficult to define and is best left under its own interpretation, on its own, without trying to put a definition to it that really is not a complete definition anyway.
