Tori is slang for cocaine, yayo, coke, or snow. The euphemism gained popularity in the late 90's in the southern California region, eventually spreading and gaining use in northern Califoria circa 2002. While the use has been largely in the California area, use of it has been reported on the east coast as well as international locations.
In addition, it can be used twice in a sentence to suggest large amounts or 'going on a bender'.
