ket stick
The use of ketamine as a recreational drug dates back to the 1970s in America. The slang term then was special K or super K, and falling down the K hole was the 1990s expression used for the mental confusion and loss of physical capacity that followed from taking too much of the drug. Apparently your legs turn to jelly and this severely limits your capacity to dance at music festivals.
Use of ketamine continues but this year Australians have been credited with hitting on a solution to the k hole — the walking stick now known in drug-taking circles as the ket stick. As one partygoer remarked, it allows you to stay on your feet for longer as well as helping you to cut a swathe through other partygoers milling around to the music.
The drug is now being called pony powder because of its use by vets.
