The 24 Hour Flu is the debilitating after effects of drinking too much liquor. It is called the 24 hour flu because you feel as if you have the stomach flu, except without the 2 week duration of the actual virus. Common causes of the 24 hour flu are lemon parties (not to be confused with the shock pic), vodka, whiskey, Jagermeister, rum, everclear, tequila or any other hard liquor. It is the most common cause of missing employees on monday because of hard partying over the weekend.

Did he call you after your slumber party?
No... and the 24 hour rule has never failed me. I guess he's just not interested...
