Growler

What happens when you combine a grown man with a few cans of beer = the growler!  Yes, this can really happen.  When you hear it, you will know.  It is a combination of talking mixed with growling or a heavy breath and a roll of the r perhaps?  Nevertheless, it is indeed a strange phenomenon.  Why does this occur spontaneously?  I suppose that question lines up with why is the sky blue and why did Tiger Woods think he could screw a bunch of trashy chicks and never be found out or why do twinkies never spoil?
