look up any word, like fellated:
 
1.
A neuropsychiatric disorder characterized by physical tics. These tics travel from the brain down through the carpal cannal causing the subject to experience uncontrolled urges to type mostly incoherent babble and useless drivel. When one finds themselves on social media sites carrying on senselessly, typing a lot but saying mostly nothing, this is known as carpal tourette syndrome (CTS).

It's basically a get out of jail free card for those times when you've typed something that you regret and can't delete it.
I blame my carpal tourette syndrome for last night's facebook rant.

I didn't mean to be so mean when I texted you, it's my carpal tourettes flaring up again.

No I'm not a racist, I have carpal tourette syndrome!
