I do this too... I think it counts as stimming in that it stimulates the act of removing an unwanted thought from one's mind. Normally what I say is total nonsense like asking myself "what should I do..." even though I know full well what I want to do (and might be in the middle of it), or something like "I will destroy the world!"... basically, just whatever random phrase enters my mind at the time. Happens most when I have an embarrassing memory.
It's definitely not tourettes, though. Whilst it might be strongly impulsive, it's not completely unpreventable.
