a terrible sickness where you feel like you shouldnt be able to walk, but somehow you can. everything on your body is achy, you get the WORST headache, a sore throat, a cough, a stuffy nose, a stomach ache, and you puke. And this lasts about a week.
Why weren't you in school last week?
-Oh, I had the flu.
