Heres an example from my .htaccess file on one of my sites.
Code:
RewriteEngine on
RewriteCond %{HTTP_REFERER} ^http(s)?://(www\.)?sexmovielovers.com.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http(s)?://(www\.)?nasty-babes.net.*$ [NC]
RewriteRule .* http://www.8thstreetlatinas.com/main.htm?id=dynastoned&p=clean [R,L]
