Bleep (who represents Coprolalia which is only present in about 10% of people with Tourette's) sometimes has a really hard time doing basic things like going to the grocery store due to the things she says and the the stuff that winds up happening. Its really embarrassing to to say things you don't mean especially when they are not socially acceptable.
One way that the artist has found is an easy way to deal with it in public is having business cards printed out that she can just hand people. Along with havening a shirt or sweatshirt that says "I have Tourette's" or something along those lines on them. This is an easy way to explain it and let people know without having to say it. They can also start conversations that lead to education creating awareness as well sometimes. People once they realize that its not meant and you can't control it have no problems.
