Turd Blossom

"Turd Blossom" (or Sand Turd) is a Texan United States term for a flower which grows from a pile of cow dung. As Turd Blossom, the term has gained fame in the United States as a nickname that was reportedly assigned by former U.S. President George W. Bush as a term of endearment for his former chief political advisor, Karl Rove.
In July 2005, several newspapers declined to run two "Doonesbury" comic strips portraying Bush addressing Rove by this nickname.
