"Man Flu" annoys me less, because there is a phenomenon (not confined to men, but in my experience more prevalent amongst them) of "You're ill," "No, I'm fine, Really, I'm fine, I'm FINE!!...[an hour later]... OH MY GOD I'M DYING" which could be termed "Man Flu" - not because said men are milking it but because it's seen as unmanly weakness to have a cold, so anything which actually makes you feel like shit must be considered equally Manly in order to justify the duvet day that results. Hence so many men claiming it's The Flu, when it's just a seasonal cold.

That said, it's sexist garbage that men feel they have to do that.
