That's very interesting. I guess I do a fake stutter at times but it's more to mock myself and belittle myself than it is to help myself, and it's usually under my breath too or when I'm alone I'd mock myself by fake stuttering. I feel it'd be hard to fake stutter during a conversation and then try to recover. I was fake stuttering with friends after having a bad stutter and then I couldn't recover after the fake stutter, I just had to stop.
