Bogan slang, meaning something is very good, or to agree with a statement that a fellow bogan is saying. Australians tend to use the term 'heaps' in objection to 'many' or 'loads' and therefore, something that is 'heaps hectic' is very good ('hectic' meaning good or nice).

It means no I don't know what you're saying I don't know because I don't have the knowledge, but yeah you could be right.

I agree with your negative statement, so I will exclaim in a negative way, and then I will give a positive reaction that I agree.

Naaah, yeah.
Stroker: I can't imagine ever using the term 'Nah yeah'

Jone: Nah...... yeah.

Heavily used slang in Australia. Used when you are reluctant to commit to a firm answer. Yeah nah is another way of saying yeah I hear you but no is the likely answer. While nah yeah is like saying I don't agree with what you saying but yeah is the likely answer.
