When you live in a place where temperatures of 40C (104F) are a regular occurrence, and temperatures of 45C (113F) and higher are not unheard of, you need to find ways of keeping yourself cool -- and your perishable food items as well, when you're out and about. As we come to the end of February, and hopefully the end of the sweltering season, I offer some Australian slang useful for keeping your goodies cool when the sun gets hot.
Esky: an insulated container used to hold ice or icepacks and keep food and beverages cold on picnics, at barbecues, the beach, etc. Known in the UK as a coolbox/coolbag and in the US as a cooler.
Usage: "If you hadn't put so much beer in the esky, we might have been able to pack a few more sandwiches."
