Prevent google bot crawling a particular post

I want to add something like this into wordpress header, but I don’t know the code.

if webpage = http://www.thefunstufftodo.com/partners

then <meta name=”googlebot” content=”noindex, nofollow”>

If anyone can help, it’s greatly appreciated.

I only want this meta tag for this particular post: http://www.thefunstufftodo.com/partners

How would I do that in wordpress?
