The most painful experience ever, only lasting for a day or two. Symptoms include diarrhea, vomiting, and unbearable stomach pains. It's extremely contagious. No vaccine, no cure, and you only gain immunity to it for a few weeks. Have fun.

A fictitious disease made up by idiots. The actual flu has absolutely nothing to do with your stomach or your digestive system.
Moron: I think I might have the stomach flu.

Doctor (or anybody with an IQ in the triple digits): No you don't because that doesn't exist. You probably have gastroenteritis.
