I haven’t already noticed, I have a particular fondness for slang. Though the phrase “23 Skidoo” was popularized in the 1890s, it is indelibly associated with the strong draft of wind that whistles around the corner of the Flatiron Building (or Fuller Building) at 23rd Street. Meaning to scram, to get away, to hightail it out of there, its association with this particular corner is characterized in this account by Sir Phillip Burne-Jones, in Dollars and Democracy, his travelogue of the United States in the early 1900s:
One vast horror, facing Madison Square, is distinctly responsible for a new form of hurricane, which meets unsuspecting pedestrians as they reach the corner, causing them extreme discomfort. I suppose the wind is in some way intercepted by the towering height of the building, and forced down with fury into an unaccustomed channel. When its effects first became noticeable, a little rude crowd of loafers and street arabs used to congregate upon the curb to jeer at and gloat over the distress of ladies whose skirts were blown into their eyes as they rounded the treacherous corner. Hanging about this particular spot soon became a recognised and punishable offence, and any one loitering there more than a few moments is now promptly “moved on” by the police. A lawsuit is also at this moment pending against the owner of this building, brought by a neighbouring tradesman whose shop-window has twice been blown in by the newly created whirlwind.
This video from October 1903 shows how strong the winds were!
