Prepare popcorn in microwave or air popper according to directions.
Melt the butter spread in the microwave.
Add the lemon juice to the melted buttery spread and mix to combine.
Slowly drizzle the butter/lemon mixture over the prepared popcorn while tossing to distribute coating and prevent popcorn from getting soggy.
Sprinkle the Old Bay Spice over the buttered popcorn while tossing to distribute as evenly as possible.
