Any container that contains a propellant that can be abused by persons addicted to inhaling such substances. So named for the infamous woman, Allison, on the show "Interdiction" who was addicted to breathing in the propellant from air-duster cans and stated, "it's like I'm walking on sunshine".
Can also be referred to as, "a can of sunshine"
Why do you have that sunshine can in your mouth? Are you daft?
