Noun A substance that causes Grunts the lowest form of Covenant in the Halo series to become powerful enough to kick the ass of anyone, including Chuck Norris. All grunts are born with enough power to conquer the known universe, however their brains are too small and weak to unlock this potential so they are stuck as the rank-and-file troops of the Covenant armies. Gruntiness is a mighty substance that lets grunts unlock their incredible power. It equally affects all beings, so if someone took Gruntiness they would become super powerful, however, Gruntiness is so powerful that any non-grunts who absorb Gruntiness will instantly being incinerated by a surge of power. The only non-grunts known to ingest Gruntiness and live are: Chuck Norris Bruce Lee Mr. T Captain Falcon Ganondorf The girl from Serenity The only way a non-grunt could not be instantly incinerated by Gruntiness is to jump into an active volcano and live. An alternate way for a grunt to be imbued with Gruniness is to do the Gruntiness Dance.
