To be jubilant is to show great joy or triumph. Contrasted with the word happy, which conveys delight but not necessarily to a high (or noisy) degree, jubilant shouts its elation from the rooftops.

Something that is typical is characteristic or distinctive of a certain type or specimen. Something that is quintessential is not only characteristic or distinctive of a type, but goes a step further to capture the pure and essential essence of it—or to embody it perfectly. Quintessential is used to talk about people or things that are exactly as one might imagine or hope for them to be, based on widely circulated and understood ideas or ideals.
