1. “Can’t Be Bothered”
There is no easy American phrase that explains that “I could do that, but no, no I don’t think I will do that, just because I don’t feel like it.” Can’t Be Bothered uses minimal effort to express minimal effort.
2. “My Shout”
Meaning: “I’ve got this round, or I’ve got the tab.” Aussies are great at not splitting checks, and just taking turns paying for things. Why are they screaming? Probably because they get the most shouty at the pub.
