JaAm is a strange, green liguid contained within a large see-through container thing found in Hawaii. It was popularized by the Transformers character Hot Shot, who no one really cares about. JaAm is said to make whoever eats/drinks it (or whatever you do to it--you're supposed to put it in your belly somehow) go temporarily insane.
"YuM JaAm! i LiK JaAm!"
