Something odd about my stutter.

Something odd about my stutter. I have a moderate stutter, it's not as visible when I'm talking with my friends, it mostly appears when talking to strangers, but what I noticed is that when get annoyed or mad with my friends for any reason and we devolve into shouting match, my stutter almost gets out of the way completely, and eventually after things calm down it waltzes back in, does this happen to anyone else?
