Should various sports tags imply "sport"?

Posted under Tags

The sport tag is poorly defined and used on such a wide variety of posts that I question its value. Its wiki (authored by a user notorious for bad wiki edits) reads like a dictionary definition and does nothing to explain how it should be used as a tag. What, exactly, are the criteria for when this tag should be used?

Does sport include individual non-competitive recreational activities? (post #3049717, post #3955657)

What about characters standing around in athletic wear? (post #1761270, post #4539011)

What about fetish art that happens to include sporting gear? (post #406963)

I'd be wary of making any implications to sport until we can address these questions and come up with a proper wiki for the tag. Or nuke it.
