I don't know if it's a show or a movie but there's a scene where a boy and a girl are at the movies and the girl is really into the movie. She keeps reaching in the bag of popcorn which is on the boy's lap. The boy then proceeds to dump the popcorn so the girl can touch his penis. The bag has red and white vertical stripes.

Chosen answer: Not sure if it's the scene you're thinking of, but the movie "Diner" uses a box of popcorn that way.
