Coprolalia is the involuntary, repeated expression of swear words. This is distinct from simple swearing in that the same words tend to be said over and over in a compulsive, repetitious fashion, not spoken in anger. The most common word is "fuck", but virtually any swear work can be heard. Coprolalia is not necessary for the diagnosis of TS. Less than 30% of TS patients have this symptom.

Definitely not. The fact is that cursing, uttering obscenities, and ethnic slurs are manifested by fewer than 15% of people with TS. Too often, however, the media seize upon this symptom for its sensational effect. Because milder cases are being diagnosed, the incidence of coprolalia will probably decrease.
