adult trick or treating

The time period after halloween when one goes to the store and buys a lot of the 50% off candy. Its adult trick or treating because you get more candy in less time but as with all adult things you must pay for it.

guy 1: Yo you going adult trick or treating later?
guy 2: hell yea!

guy 1: better get there before all the good shit is gone haha
Guy2 : yeah haha nobody wants to get stuck with the shitty almond joy pack.
