Position a large pot or popcorn maker over medium-high heat. Add the popcorn kernels and cover with a lid. Shake gently until popping slows, then remove from heat and transfer the popped popcorn to a large mixing bowl, ensuring all unpopped kernels are discarded. Observe the fluffy, white popcorn filling the bowl, ready for coating.
Pour the melted butter evenly over the warm popcorn, and gently toss with a spatula or large spoon until the popcorn is well coated and glistening. The popcorn should appear shiny and slightly sticky, with a gentle aroma of butter filling the air.
