ninja linking 

Using a false address as the text mask for a hyperlink with the intention of keeping actual hyperlink secret until too late.

using VB code;

url=www.ratemypoo.comwww.coolbeans.com/url

the above code would display as "www.coolbeans.com" but once clicked, the "www.ratemypoo.com" link is opened.
