KudoZ: asking

I see a "Squash" button under a KudoZ question I have posted, what does that mean? 

If you have posted a KudoZ term help question and it has not received an answer, you will have the option to "Squash" or remove the question until it receives at least one answer. This allows users to remove mistakenly-posted questions without the assistance of site staff, a moderator or KudoZ editor.
