We're not completely sure where the word "nifty" comes from, but we do know it might be related to the word "magnificent" (meaning "wonderful, fantastic"), and we know that people have been using the word "nifty" since the year 1865. So, as slang words go, "nifty" is here to stay. It's a popular word.
