80% of every unique sentence I'll let it rip, I also got the full on head movements like twitching to the right or towards who I am speaking to, coupled with shutting my eyes shut really hard and shutting them harder in sync to the stutter. Worst was when i was going to cash a check at a Kroger and the cashier girl told me "you don't have to be nervous, its ok." I know she didn't mean anything bad by it but that shit supremely pissed me off at the time, only reason I didn't say anything was because I didn't want to make her have the uncomfortable realization that the dude in front of her had a speech impediment.
