Example Sentence

Did you know?
English speakers of the mid-19th century already had the term "snorter" at their disposal if they wanted a colorful term for something extraordinary, but that didn't stop speakers in the U.S. from throwing the verb "rip" onto the front of the word to create "ripsnorter." And they didn't stop there: By the time the 20th century had reached its quarter mark, U.S. speakers had added "hummer," "humdinger" (probably an alteration of "hummer"), "pip" (from "pippin," a kind of crisp, tart apple and a term for a highly admirable person or thing), and "doozy" (thought to be an alteration of "daisy") to the catalog of words for the striking or extraordinary.
