The Pineapple on Pizza debate is one of the internet's most enduring and divisive food wars, pitting traditionalists against adventurous eaters. While the combination of ham and pineapple, known as Hawaiian pizza, was actually invented in Canada in 1962 by Sam Panopoulos, it remains a lightning rod for social media conflict. The meme usually highlights the extreme reactions people have toward the topping, ranging from absolute disgust to passionate defense. It is frequently used to represent any subjective topic where there is no middle ground, often featuring cursed food images or intense reaction templates to emphasize how seriously people take their pizza toppings.
