A word used to articulate a sound when a simple grr or growl doesn't quite get the point across. Can be used in frustration, anger, and just about any other emotion. Can be elongated to suit one's needs, but must always be at least two syllables long.
"Grrr-buh!!! i can't get the top off of the salsa jar, I need salsa in my tummy!"
