In Canada, a filthy, drunken Native/First Nation person, so called because they'll slam back any intoxicant they get their hands on (liquor, Lysol, etc) to achieve the maximum effect, and also so they don't have to share with fellow chugs. Typically found hanging around panhandling in front of liquor stores and sleazy bars, or passed out anywhere convenient.
Those damn chugs will steal anything.
There's a chug passed out on the hood of your car again.
