Similar to jungle juice in the United States, Yukaflux is a regional Canadian term for a communal drink consisting of a variety of alcohols (usually Vodka and Rum but can include almost anything from schnapps to wine), drink mix/juice and chunks of fruit left to sit overnight. The drink is ritually served in an unconventional container, such as a rubbermaid tub, cooler, bathtub.
