I had been under the apparent misapprehension that the term man flu was used to distinguish it from bird flu or swine flu etc.
But according to Wikipedia this is how it is described.
Man flu is a pejoratively used phrase that refers to the idea that men, when they have a cold, exaggerate and claim they have the flu. Whilst a commonly used phrase in the UK and Ireland, it is referred to in other cultures and there is a continuing discussion over the scientific basis for the phrase.
A couple of people have recently told me they had man flu. Any ideas as to what they might have meant?
