Man Flu is a crippling and debilitating disorder indiscriminately striking down male members of the human species without warning. The illness is often referred to pejoratively by female members of the species who are in fact immune from the illness as man flu is now known to exclusively attack the XY chromosome carrier. If Man Flu is kind enough not to kill the infected party it will definitely leave him weak, sick, hurting everywhere and in dire need of TLC.Definition taken from... http://www.manflu.info/
Medical professionals now also widely recognise that self diagnosis by the sufferer is the best means of identification as the symptoms of Man Flu are far more severe than the simple common cold which predominantly targets the XX chromosome holders (i.e. females). This goes some way to explain the cynicism some women display towards their male counterparts.
Hubby is presently at Stage 2...
Stage 2 - It's not a cold, it's the 'flu. Your beloved will barely be able to lift his fingers to work the remote control by now. There will be dramatic displays of coughing and chest holding. He will present a red and sniffly nose, and a phantom fever. Do not mention (begin sarcasm) Man 'Flu (end sarcasm). Instead continue to serve comfort food and provide him with a selection of men's magazines (such as FHM or Maxim) to take his mind off the illness ravaging his poor body. You may also be required to gently dab his forehead with a lightly dampened sponge or massage his feet. This life threatening stage may last from three to five days.
