You can read this article for yourself, but I prefer the summary from “The Week”, where it came to my attention:
Bad week for: translations, as PETA launched an anti-dairy campaign urging Hispanic youth, Eche la leche. The phrase, literally translated as “dump milk,” is slang for ejaculation.”
Yet another case where marketing screws up a translation. It took Chevrolet years to figure out why the Nova didn’t sell in latin America. The makers of this detergent probably wonder why it doesn’t sell in the US.
