Can someone please give me a proper definition for the term?
What I know so far is that it is an input box that allows the user to enter any data to categorize something. Is that it?

A:
Free tagging (at least how I use it) is when you expose a field that lets a user add any tag to the content node. Essentially you are allowing anyone with permission to add a custom tag to describe the content as they relate to it.
This is opposed to creating a rigid hierarchy of categories.
The most common application of free tagging is to let your users describe the content and then create "tag clouds" out of the results.

An obvious example being this website, that allows you to tag your questions any way you like.
