What do the Dutch call Dutch Courage?
The phrase Dutch courage is a slang term for courage gained from intoxication by alcohol. It is synonymous with liquid courage. The term is purported to have its origins in the battles of the seas where the Dutch navy is said to have been feared among all other navies (especially among the later rival, the English navy – later the British navy) because of its courage, and it was rationalised that they must have drunk alcohol before battle to relieve fear.
