I just think it's a great new nickname for Dick Cheney: Blood Clot!. From everything2:

"Blood Clot" is the most virulent insult in Jamaican Patois English. It is similar to 'fuck' in usage, but does not change form for different parts of speech. Blood Clot has entered the slang lexicon in other dialects of English through the Rastafarian sub-culture.

It can be an noun, as in "Shut up, blood clot," or, more commonly, an adjective, as in "The blood clot government is cracking down on the growing of the herb."

I got this idea from a comment in this Rolling Stone blog post about the distant potential of a Bush Impeachment (600+ days and counting): "As for Cheney becoming prez… C’mon bloodclot!!! make your move!!!"
