Etymology
The origin of the term cockamamie is not confirmed. It's believed that it's a corruption of decalcomania, the process of transferring a design from a specially prepared paper to another surface. In the beginning, a cockamamie was a fake tattoo, moistened with water and applied to the wrist. How it took the sense of something pointless is uncertain. It's perhaps been influenced by such terms as cock-and-bull or poppycock.

It wasn't the company's 2001 loss of $11.8 billion (U.S.), the largest in French history, that did me in. Nor the cockamamie convergence idea that saw a one-time water utility become the world's second largest media and communications company ..." — Jennifer Wells; Crooning Set Tone for Messier Ouster; The Toronto Star (Canada), Jul 3, 2002.

"For these reasons, the delegates were unwilling, as late as two weeks before the end of the convention, to endow the presidential office with substantive powers.
