"That party was full-on."
Where "Full-on" Comes From
A straightforward extension of standard English "full on" — running at full capacity — stretched by Australians to describe anything intense, chaotic, or overwhelming, whether that's good, bad, or somewhere in between.
Its flexibility is part of the appeal: a full-on week, a full-on argument, and a full-on party can all mean quite different things depending on tone.
How Aussies Actually Use It
Used to dial up almost any description — a full-on schedule, a full-on storm, a full-on personality — always signalling that whatever's being described is more intense than usual.
Tone of voice usually tells you whether it's meant as a complaint or as praise.
