Nah, Brah
It’s like saying 'heaps hectic' but in a more annoying way. Australians use it like it’s a real language.
Nah, Brah, that party was heaps hectic. You should’ve been there.
Nah, Brah, this game is heaps hectic. You’re gonna lose.
Nah, Brah, that cake was heaps hectic. You should’ve had some.
