what does nacko mean?
i want the meaning?
For sure must be naco. If so, it's used in México and is quite pejorative, has a wide variety of meanings, each person can have it's own interpretation. It's some similar to "redneck".
"Nacko" is not a Spanish word, as far as I can tell. Perhaps you mean "narco", which is a slang word used to refer to drug traffickers.
"peyorative" is actually spell "pejorative"
And I also agree w/ Toni's answer.
I agree with Toni. Naco is a peyorative word used in Mexico.
