The hallmarks of Tourette's syndrome are repetitive, involuntary movements (motor tics) and utterances (phonic tics) that constantly change in number, frequency, severity, and anatomical location. The Tourette Syndrome Association describes tics as movements or sounds "that occur intermittently and unpredictably out of a background of normal motor activity". The tics of Tourette's characteristically come and go. Waxing and waning — a natural increase and decrease in severity and frequency of tics — occurs differently in each individual. Tics are described as occurring in "bouts of bouts", which vary for each person.
Coprolalia (the spontaneous utterance of socially objectionable or taboo words or phrases) is the most publicized symptom of Tourette's syndrome, but it is not required for a diagnosis of Tourette's. Fewer than 15% of TS patients exhibit coprolalia. More common tics are eye blinking, throat clearing, coughing, neck stretching, and shoulder shrugging.
So, with regards to your question...I echo the sentiments of s-m-w (above post)..."they would surely be aware of these words" or I suspect they would come up with something on their own that was of comparable insult.
