it must be revealing something about my neurology wrt language processing.
Like, I don't consciously process grammar of the vast majority of things I say, so perhaps there is part of my brain that can get a concept shot into it, and formatted English vocalisations come out?
I would have assumed tic origins were like, closer to where mouth/muscle/actions are processed and further from thoughts/concepts but I suppose if that were true suppression wouldn't ever work.
