"Going dotty" is a British phrase that Aussies have adopted with gusto, describing that moment when someone starts acting a bit bonkers, as if they've misplaced a few marbles on the way to the pub. It's like when your mate suddenly decides it's a good idea to wear flip-flops in the snow, or when your grandma starts knitting beanies for her potted plants.
In Australian culture, "going dotty" is the perfect way to explain those little lapses in logic or unexpected bursts of eccentricity that make life interesting. Aussies use it to describe everything from an over-enthusiastic footy fan who paints their entire body in team colors to a surfer who decides to catch waves during a thunderstorm. It's that moment when someone acts a bit loopy, but in a way that's more charming than concerning. So when an Aussie tells you they're "going dotty," it usually means they're about to do something wonderfully weird. Hold on tight, because it's bound to be a wild ride!
