Slang for: is not, are not, has not, have not, was not, were not, will not, would not, can not, could not, etc. It is a word which basically means NOT, depending on what the circumstance is. She ain't going. S he is not going. He ain't got any money. He has no money.. Bill ain't at the party. Bill was not at the party.

"What does it mean?" It means 'isn't' or 'aren't' and is sometimes used for 'have not' It's considered BAD English I ain't got a pencil = I haven't got a pencil It ain't raining = It isn't raining.

Thank you all. I heard a Brett Dennen song entitled: "Ain't no reason", that I find very nice,interesting text.

It means 'isn't' But you shouldn't use it It isn't proper English, it is used when people are too lazy to speak properly :D
