Explanation

A lollapalooza is anything that's a really awesome member of the category it's in. If you went to a great party, with marvelous music and fantastic food, you could describe it as a lollapalooza. This word has been around since at least the late 1800s, and it's been spelled many different ways. "Lallapalootza," "lallapaloosa," "lallapaloozer," "lollapaloosa," and "lalapalooza" are just some of the versions you might see in older texts. The word's way of being pronounced has also been different, with the first "a" sound sometimes being pronounced like "cat" and sometimes being pronounced like "car," and with the "z" sometimes being pronounced as z and sometimes as s. Its origin is unknown — a real lollapalooza of a mystery.
