About a year ago I had a young guy with Tourettes come in because he had a new tic that made him shape his hand like a pretend finger gun and poke the side of his head. He ticced when he was holding a pencil and jabbed his eye with the lead. Yeah ouch.
With Tourettes anxiety triggers more tics and certain tics get triggered by environments or people like somebody yelling BOMB in an airport or PIG at a cop. The cussing tics are rare but people who have those tics post a lot more and that is why it looks like they all cuss constantly.
He had the coprolalia and copropraxia and kept flipping me the bird or making jack off gestures and saying FATTY and N I G G E R and HELLO NURSE when telling me how he hurt his eye. I ignored the tics after I said I knew he had no control of them. They got so intense he had to be sedated to have his eye looked at properly because one of his tics jerked his head down till his cheek touched his shoulder and it kept happening when I opened the sore eye to look for bleeding.
He severely scratched his cornea but didn't hurt the rest of his eye so he got antibiotic eyedrops and a patch to protect the eye from infection and tics. He came back a week later and gave me a gift card for the trouble because he felt bad about ticcing N I G G E R at me. Class act, man.
Btw N I G G E R wasn't his best tic no his best ones were BATMAN LIKES PONIES and BRONIES DID 9/11.

I almost pissed myself laughing.
