ELI5: Why does someone with verbal Tourette’s often use swear/crude words? Society is the only thing that makes those words taboo, so why does it seem people with Tourette’s get stuck saying them?

There is actually a specific part of the brain that is dedicated to housing these sorts of 'taboo' concepts. Anything that we're brought up to believe is taboo more or less gets stored here.

The specific variety of Tourettes that causes the 'involuntary swearing' tick (there are many more cases of this disorder which do not exhibit that specific tick) apparently causes people to access these specific regions of the brain at random or under certain conditions.

This is the least common variety of Tourettes, and it is much more common to see people with physical ticks (compulsions to move their hands, eyes, etc., In specific ways and so forth).
