The man flu is where a dude will feel under the weather for a few hours/half the day after sitting outside in the cold for hours while smoking half a pack of cigarettes, some weed, and drinking jack Daniels. The man flu is also having a sinus headache.........that’s it. The man flu is a serious illness that should be announced to all and taken seriously. The man flu has no actual symptoms, when confronted about the man flu it can only be described as “ feeling really sick”. There is no cure for man flu.
My husband has the man flu. He has the sniffles and has dramatically thrown himself on the couch and called out of work.
