Red-faced officials at General Motors in Canada have been forced to think of a new name for their latest model after discovering it was a slang word for masturbation.

GM officials said they had been unaware that LaCrosse was a term for self-gratification among teenagers in French-speaking Quebec.

The article describes a copuple of similar issues with product names as they cross the language barrier. The most amusing story was the poor reception of the Ford Pinto in Brazil which was attributed to the fact that in Brazilian Portuguese slang, pinto means "small penis".
