"Turd Blossom" (or Sand Turd) is a Texan 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 sobriquet 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.
In the 2014 film Guardians of the Galaxy, main character Peter Quill calls the villain a turd blossom as a distraction.
