ita, this will do what you want wrt fuckers.com:
RewriteEngine on
RewriteCond %{HTTP_REFERER} ^http://(.*.)?fuckers.com/.*$ [NC,OR]
RewriteCond %{HTTP_REFERER} ^http://(.*.)?asswipes.com/.*$ [NC]
RewriteRule .*\\.(jpg|jpeg|gif)$ [link] [R,NC,L]
RewriteCond %{HTTP_REFERER} !^$
RewriteCond %{HTTP_REFERER} !^http://(.*.)?buffistas.org/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(.*.)?worldcrossing.com/.*$ [NC]
RewriteCond %{HTTP_REFERER} !^http://(.*.)?provocateuse.com/.*$ [NC]
RewriteRule .*\\.(jpg|jpeg|gif)$ [link] [R,NC,L]
The main point being the L flag in the RewriteRule which tells it this is the Last command and stop processing this chain. Oh, and the order of the commands is important, otherwise fuckers.com will match the second chain. For extra credit, I wrote the rule so that you can add more domains to the list using the OR flag (see asswipes.com above).
You might just want to consider forbidding the hotlinking altogether thusly:
RewriteRule .*\\.(jpg|jpeg|gif)$ - [F,NC,L]
