noun: a term that was used in the 1950s and 1960s by gents on Skid Row for the
delirium tremens, which are sometimes fatal. It probably referred to
the illusion that things were moving when they were not and
the feeling that your skin was crawling away. When a person feels the snakes coming on, it is time to let up a little, sip a little low test, white port and settle your nerves.
