What "Twitter" meant in 1874

John Camden Hotten's The Slang Dictionary: Etymological, Historical and Anecdotal was published in 1874, and is available in Project Gutenberg's archive. It's a nice piece of work, as this post on EbookFriendly illustrates, with choice definitions from a bygone era for "Pin," "Twitter" and more.

pin: "to put in the pin," to refrain from drinking. From the ancient peg tankard, which was furnished with a row of pins, or pegs, to regulate the amount which each person was to drink. Drunken people are often requested to "put in the pin," from some remote connexion between their unsteadiness and that of a carriage wheel which has lost its linch-pin. The popular cry, "put in the pin," can have no connexion with the drinking pin or peg now, whatever it may originally have had. A merry pin, a roysterer

twitter: "all in a twitter", in a fright or fidgety state

poll: a female of unsteady character; "polled up," means living with a woman in a state of unmarried impropriety. Also, if a costermonger sees one of his friends walking with a strange woman, he will say to him on the earliest opportunity, "I saw yer when yer was polled up"

cool: to look

The Slang Dictionary from 1874 is hilarious (and you can download it for free)
