So, how did you score back in the forties?
In most U. S. cities the marijuana salesman peddles his cigarets to known clients in public places. He is known to his clients as a "pusher." His clients are known as "vipers." Etiquette between pushers and vipers is necessarily delicate. When he wants to buy, the viper sidles up to the pusher and inquires "Are ya stickin'?" or "Are ya layin' down the hustle?" If the answer is affirmative, the viper says, "Gimme an ace" (meaning one reefer), "a deuce" (meaning two), or "a deck" (meaning a large number). The viper may then quietly "blast the weed" (smoke). Two or three long puffs usually suffice after a while to produce a light jag. The smoker is then said to be "high" or "floating." When he has smoked a reefer down to a half-inch butt, he carefully conserves it in an empty match box. In this condition it is known, in Mexican, as a chicharra, or in English, as a "roach."
