In the words of the immortal John Scalzi:
""Choad Mongering Krill forgeter" -- Now we're talking. This insult works on so many levels. "Choad," of course, is a great piece of slang, not nearly utilized to its full potential in everyday invective, so it's still a nice fresh slap to start the insult. "Mongering," likewise a great verb: Sounds great, first off, but also obscure enough to thrill -- after all, who mongers very much anymore? "Krill forgeter" implies that you're so hard up you'd screw a baleen whale's morning snack and, inasmuch as krill are microscopic shrimp, it also says you have a dinky little wanger (otherwise, of course, how could you forget a krill? It'd just break apart). Finally, the phrase lends itself to multiple variations: "richard Whoring Shrimp Porker," for example. The possibilities really are endless."
I also use 'roostersock' a lot
