Administrator, please remove this page!

This template puts this page in the category of pages to delete, deletion being an operation that is for administrators only.

A reason for the proposed deletion should be given, as the first (and so far only) argument. With a reason, e.g., {{remove|it's spam}}, the above alertbox changes to something like this:

Administrator, please remove this page, because it's spam!

This is a template. There are many others. See Category:RCTemplates for a complete list of templates.
