A rare strain of flu so powerful and so deadly it can only be matched by the Bubonic Plague and Aids. A incurable virus which has adapted to only effect the "XY" gene found in men. The virus attacks the immune system 10,000 times harder than the average flu virus, causing excruciating pain for the victim. Man Flu has no cure and prayers can save the forsaken life of the infected. The often deadly virus is mostly laughed at by women who sadly cannot contract "Man Flu"
Woman: Is he ok?
Doctor: I'm afraid not, I'm sad to say he has Man Flu
