What era or genre are you getting the pop culture from? Twinkies at least have only been a joke in media for at least 15 years because of zombie survival stuff, and longer as a ‘haha look at the fat kid’ before that.

That movie is nearly 40 years old though and probably marks around the time Twinkies shifted from a snack to a meme
