Just words

Some words or catchphrases—many of them made up—sound terrible to me; therefore I’ve endeavored never to use them, except now, where I list them:

• millennials — Just another word, I suppose, for self-absorbed people. I think this distinction—calling people Generation X, Y, or millennial based on the year they were born—is all made up.
• netizens — I prefer “internet users,” or “people” in general. Everyone I know has encountered the internet at some point.
• twinning — Use “twins.” This is acceptable, though, when talking about some process after fertilization.
• adulting — It sounds so immature. I’ll only use this if pediatric-ting becomes a thing, too.
