What causes Tourette Syndrome?
Fuck if I know. Shit, bitch, damn.
Here’s a f#@$ing link that I found using a c@#!sucking search engine. Not a whole lot of f#@ing #!+ there, G@#dammit.
@$$HOLE!! F@#*!! $#!+!!
Not all Tourette’s is characterized by uncontrolled swearing. That is the exception rather than the norm.
Like I didn’t f#@$ing know that. 
Actually from what I understand it's mainly characterized by severe tics.*
