You mean a s s s s stutter.
All joking aside, I have never stuttered, but I used to mentally stutter. If that makes any sense ? When I reasoned with myself (ie thinking) I would occasionally s s s stutter in my head ! Bizzare. Then again, I always knew I was a whack job!
eP. (The voice of r r r reason) Bugger, it's s s started a a again.
*please don't think I am taking the piss out of anyone who stutters. Nothing could be further from my daft mind.
