voluntary tourettes
Voluntary Tourettes is a disease that causes people to say outlandish, intrusive, offensive, or overly Freudian comments; even though they know better and could easily restrain themselves. It can inflict any age, sex, or race. However, it has long been recognized to be more prevalent in mother-in-laws. Symptoms can be mimicked or compounded by alcohol.
