Yes, cow pie, as in giant slab of cow crap.

From Obama’s speech last night in Des Moines, Iowa:

Now, I know Governor Romney came to Des Moines last week; warned about a “prairie fire of debt.” That’s what he said. (Laughter.) But he left out some facts. His speech was more like a cow pie of distortion. (Laughter.) I don’t know whose record he twisted the most — mine or his. (Laughter.)
