a container for keeping food or bottles cool
a long drink, especially a mixture of wine, fruit juice, and soda water
prison or a prison cell
the cooler was a dark, claustrophobic room
showing no friendliness towards a person or enthusiasm for an idea or project
he gave a cool reception to the suggestion for a research centre
fashionably attractive or impressive
he made no concessions to fashion, yet somehow he was hip and cool
I always wore sunglasses to look cool
used to emphasize the size of an amount of money
research for a new drug can cost a cool £50 million
