Facebook referrer?

If my profile is let's say facebook.com/michael332

Someone navigates to my profile page which is facebook.com/michael332 and clicks on http://whatismyreferrer.com that I have posted to my wall on a status update.

would the referrer be facebook.com or facebook.com/michael332?

Because of FB's practice of wrapping outgoing URLs the referrer would actually look like
It would look like that if the click originated from your friends news feed as well.
