Nuovo slang, vecchio slang

Recently, we stumbled across this great thread at MetaFilter discussing current-sounding phrases that have been around for much longer than we think, so we did a little digging of our own to see which of our most everyday, contemporary slang words are actually rebranded anachronisms from the good old days. 

Cool – This is one of those words that never gets old, and it has what seems like a million slightly different connotations. According to the Online Etymology Dictionary, its earliest slang meaning dates to 1728, to describe large sums of money, a usage still in circulation. It started to mean “calmly audacious” in 1825, and “fashionable” in 1933.

Hanging out — The colloquial usage of this extremely common contemporary term has been recorded as far as 1811.

Psyched — “Psych” has long been short for “psychology,” used by students in that way since 1895. In 1934 the phrase “psych out” came into parlance, and in 1968 one was finally able to get “psyched up.” flavorwire.
