The line comes from a popular children's food song used in classrooms and on kids video channels to teach likes, dislikes and food vocabulary. Each verse pairs a normal food with ice cream to create an intentionally yucky combination, then encourages children to answer yes or no. Clips of the broccoli ice cream question later spread on soundboards and in short videos because the combination is so unexpected, making the short sung question reusable as a joke about strange tastes and disgusting desserts far outside its original lesson.
