Any drink mix of 2 or more liquids meant for drinking in a cylinder-ish container can be considered a "Ghug Jug", mostly used with drugs to mask the drugs flavor. A example of this is "Lean".
I don't like the taste of my meds so i may put them in a "Chug Jug"
When someone is passed out, put a gask mask on their face and connect tubes to it. Stick the other end of all the tubes into other participating people's assholes and siphon the butt fumes into the gas mask of the sleeping person.
Bro my friends hit me with a chug-jug last night.. shit was wild.
