You can toss that mix tape you were hanging on to for sentimental purposes because the folks behind the Oxford English Dictionary have decided no one even needs to know what a "cassette tape" is anymore. The term is being removed to make way for new additions like "sexting," "retweet" and "mankini." That's a fabulous idea, because parents never confuse their teen by rambling on about cassettes, but references to a bathing suit introduced in Borat and never worn seriously by a single person come up all the time.
