I'm getting frustrated thinking about this

I say that. I'm American

I'll spill the secret ok it's a demonic sacrifice

Americans also say this

Have a good day

Mmph! MMPh! MMMPHHH! Okay okay! It means have a good life

'Orright mates its time to get true blue Aussie in here. Sure, redbacks hide in the corners and koalas may be the cute killers waiting to rip your eyes out, but it ain't so bad. I mean, look at them 'roos! Smell them prawns and the ocean air! Make sure you remember your sunscreen, or at least a cork hat. (Only Aussies will know what a cork hat is)

It means have a good day! -from an Australian

That "saying" is said in every country where people speak English. So shut up

BEWARE OF THE DROP BEARS

Yeah there are a lot of people in the US how say that
