I read “man flu” and think of how women perceive men as being whiny weak little bitches when they get sick. Not just having the flu.
Never heard the term, but apparently there's also the German Männergrippe. Hmm... and apparently it means to emote a simple cold into a serious flu. Well, that I heard of .
Never heard of Man Flu before, but my wife will call me a pussy when I get the flu.
Influenza is particularly dangerous to the elderly, young children, and people with compromised immune systems, but, it affects both genders the same.
I haven't taken a sick day in ten years.
To be honest, when I first saw the thread title, and before I read titchgamer's link, I was wondering if this was going to be about some kind of male PMS thing.
