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).

Bogan 2- Yeah, Nah. Heaps hectic Brah.
