Pop popcorn as directed on package, allow to cool.

In a large bowl, combine potato chips, pretzels, sandwich cookies, and popcorn. Using your hands, crush mixture into small pieces.

Melt butter in a large saucepan over medium heat. Add mini marshmallows and stir until completely melted and smooth. Pour melted marshmallow mixture over popcorn and stir to coat. Add mini m&ms and fold to incorporate.

Spray hands with nonstick cooking spray and shape 1 cup of popcorn mixture at a time into football shapes. Transfer to a parchment-lined baking sheet and let set.

Microwave chocolate chips in 30-second intervals, stirring between each interval, until melted and smooth. Transfer melted chocolate to a zip-top bag. Cut a small hole at the corner of the bag and pipe lines resembling laces onto each popcorn football.

Wait for the chocolate to set and serve.
