##### SUMMARY
When I read the `copy` documentation, I couldn't work out what it meant.  Unfortunately, this meant it sounded like it might be a weird sex joke.

It doesn't sound like a big problem, but in an ideal world, I think we should prefer to avoid weird sex jokes in an alias for a parameter called `force`.

##### ISSUE TYPE
- Feature Idea

##### COMPONENT NAME
copy

##### ADDITIONAL INFORMATION
Issue search tells me "thirsty" was added as an option to the `get_url` module.  In that context, it is appropriate.  But in the context of the `copy` module, it does not make sense, because `copy` only works in the upload direction.

The first three pages of Google Search results (Ansible thirsty) show people using "thirsty" for downloads only, not uploads.  Similarly for GitHub code search (copy thirsty language:YAML).
