What is coprolalia?
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.
