A Fat Shat is piece of excrement that has built up so much pressure in its time in the small intestine that, on release, reaches a speed of over 35MPH. Fat Shats can often cause damage to the toilet, usually cracking the porcelain. Fat Shats are usually as large as a small football. It is common for Fat Shats to be released in someone's pants when they are hit by a strong force, hearing shocking news, or possibly just when one cannot possibly hold it in any longer
