A jacket used to sneak outside
food into the cinema. These type of jackets are usually
big and puffy and have numerous (deep) pockets to conceal any
food stuff.
Anything with (deep) pockets will do just as good.
The cinema jacket should not be stuffed directly outside the cinema.
Sadly the cinema jacket is good for the
cold/wet days.
Cargo pants/shorts, work just as good but have limited pockets.
Don't overload the pockets and make sure the
food is concealed before entering the cinema
Don't make a habit of wearing a stuffed cinema jacket, they'll get suspicious and you could be banned
person 1: "Let's go see a
movie!"
person 2: "Yep.
Got your cinema jacket?"
person 1: "Right here" *opens jacket pockets to reveal
bags of lollies from the supermarket*
