The Grunter is a rude little piggy! He lives to root and shit and no law of god or man can stop him. Is he a man? Is he a beast? Nobody can say for sure! All we know for certain is he's racist.

The Grunter is a nasty hoggish fuck that loves rooting and shitting. This character doesn't have any redeeming features at all, and no other interests or passions.

The Grunter is first mentioned in Boonta Vista episode 259 - "Here Comes the Grunter (with Tom Walker)".

The first mention of “a grunter” dates to episode episode 75 - "Dead Posts Society", in which a since-deleted Tweet from a former Australian Greens staffer is described as part of a segment on Australian politics.
