This is when someone with the surname "Finch" excretes toxic chemicals into the local atmosphere. These chemicals contain chemicals such as Methane, which can cause dire effects, For Instance, Cholera, Diarrohea. These chemicals can be excreted via the rear end, sweating, or from wearing sewage clothes, such as a fake Arsenal shirt. Unfortunately, there are no known cures for this unfortunate disease, but a Deodrant can, and a bath would be very helpful
