My $.02:
As others have stated, a grunt will usually punctuate with a few expletives between the growls, barks, and "hoahs", and it took me a couple of years to break the habits (some of which still remain after 19+yrs) [LOL]. The guy was obviously passionate, and emotions took over his brain/mouth. Who hasn't had that happen?
Either way; another scumbag was exposed (I think they smelled blood at the AR670-1 blank stare), which I think should be the main point.
