Australian and New Zealand slang for underpants — the underwear you're wearing under your 'daks' (trousers).
Australian and New Zealand slang for underpants — the underwear you're wearing under your 'daks' (trousers). While 'daks' is itself Aussie slang for pants or trousers, 'underdaks' logically extends this to mean the garment underneath them. It's unpretentious, cheerful, and quintessentially antipodean — exactly the kind of word that makes Australian English so much fun. Used freely in casual conversation and carries zero embarrassment factor.

Trousers or underwear.
Australian slang for tracksuit bottoms — the comfortable, elasticated trousers you throw on for a jog, a lazy Sunday, or a quick trip to the shops when you simply cannot be bothered to find proper pants. 'Daks' is classic Australian slang for trousers, and 'trackie' is the abbreviated form of 'tracksuit', so trackie daks is a perfectly logical compound. It's one of those words that feels quintessentially Australian — relaxed, practical, and entirely without pretension.
