A "GT" (golden triangle) mum is a mother who lives in the western suburbs of Perth, Western Australia. These mums are often dressed in active wear for their daily chai latte on napolean street, or to drop their kids of in their land rover at scotch. They also could be consider "milfs" due to their self endulgent lifestyle, silicon breasts as well as frequent use of zanex. They live in the golden triangle of Perth, usually belong to golf/tennis/yacht clubs, where their wealthy sugar daddies fund their camilla dresses, cleaners, tennis lessons and their intense social lives.

gt mum 2: Thankyou darling, just from the shop in Claremont quarter. Should I order you a chai latte with soy?

Waiter: ah look at those gt mums
