What is the Big Mac Chant?
The Big Mac Chant is:
"Two all-beef patties Special Sauce lettuce cheese pickles onions on a sesame seed bun."
“The Big Mac is a global icon and one of our most popular menu items, so it only felt right we celebrate its rich heritage with old and new generations of Big Mac fans, while creating even more feel-good moments for our customers," said Samantha McLeod, Marketing Director for McDonald’s Australia.
“It’s harder to say than it is to eat, but the faster you say it, the faster you win, so the only question is: can you say the Big Mac chant in four seconds?”
