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.

Get the stomach flu mug.
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.

A form of influenza that results from catching a virus and the inflammation of the stomach and intestines, also known as gastroenteritis, and usually lasting from 1-10 days. Common symptoms are vomiting, diarrhea, fever, lack of energy, and nausea. Unfortunately, the stomach flu often leads to a series of weaker stomach illnesses and diarrhea that can last for another two to three weeks, but vomiting doesn't always occur during these "aftershocks".
Even though there are no cures or vaccinations available for this, there are still home remedies, however. These include clear, carbonated beverages including Sprite, Sierra Mist, and 7-Up. In addition, there are foods that are easy on the stomach such as crackers, chicken noodle soup, white rice, bananas, and turkey. One of the best things that can also treat it is getting lots of sleep.
On August 30, 2005, the day after the poor folks in New Orleans got struck by Hurricane Katrina, I came down with the stomach flu, and it took me three more weeks after that to fully recover.
