"dudery" and "babe", on her list of 16 words that are much older than they seem.
She cites a 1889 phrase -- "The Pharisaical dudery which presumes to deny her (woman) a place in the world...equal with man" - to show that the sense of the usage over the centuries is the same.
"Babe", used in the sense of "hot chick", has a very 1970s ring to it. But this sense of babe has been around since the early 1900s. The OED gives a quote from 1915: "She's some babe."
Other dated but widely used words on her list are "funky", "hipster", "frigging", "booze" and "tricked out".
"Booze" has been a general slang for alcoholic drink at least since the 1850s, and it has a longer history as a Middle English verb "bouse," meaning "to drink excessively" in the 1500s.
