Can anyone tell me what nenora means in Mexican Spanish?

I'm beginning to think my friends made it up. Please help, this word is plaguing me.
I don't mean to be offensive by saying Mexican Spanish. It's just that my Columbian, Puerto Rican, Peruvian, and Spanish friends have never heard the word, but it was explained to me as a word used in Mexico. Different countries have different dialects, ya know. I am doing my best to be culturally sensitive, not offensive...so relajate dyani
