Where "Ant's Pants" Comes From
"Ant's pants" is Australia's own spin on a wave of cheerfully nonsensical American compliments from the 1920s and '30s, like "bee's knees" and "cat's whiskers" — phrases that used a small, oddly specific animal detail to mean "excellent."
The Australian version is first recorded in the 1930s, appearing in newspaper advertising as early as 1933, and has stuck around ever since as an affectionate, slightly old-fashioned way to praise someone or something.
"Have you tried her lamingtons? She's the ant's pants when it comes to baking."
How Aussies Actually Use It
It's a warm, often cheeky compliment — telling someone they're "the ant's pants" is a way of saying they're brilliant, impressive, or held in very high regard.
It works for people and things alike, from a talented mate to a particularly good meat pie, and it's usually said with a smile rather than total seriousness.
