Fear gas is the gas that you spray out of your butt after eating a combination of foods and enjoying drinks that cause a painful mix of gas.

Fear gas can also clear out a few aisles in a store, give you more space on a crowded train, and is a simple way of getting back at your friends after they prank you.

Also, things such as a combination of hot wings, chili dogs and beer can produce fear gas.

Bob: Some shopper sprayed some fear gas while he was in aisle 6.
