Pineapple Pizza Effect
1. The pineapple pizza effect is a social phenomenon where a number of people express an ungrounded aversion towards something, although they do not actually share this aversion personally. The term originates from the strong rejection of pineapples on pizza by people, despite not actually disliking it or having a preference. A "pineapple pizza" is a moniker used for things that are subjected to this phenomenon.
Often stemming from a desire to fit in or to exclude a particular group, this sudden development of strong opinions are only expressed verbally. When encountering a "pineapple pizza", people demonstrating this behavior are characterized to be instinctively driven to quickly react negatively, usually unwarranted, and unable to articulate the reason for their preference. When confronted with the opportunity to partake of the "pineapple pizza", it is expected that they would, despite what they say.
2. Since the cool kids don't like it, I now don't like it too, even though I do.
Examples of this phenomenon:
• Hating pineapples on pizza, despite eating the most Hawaiian pizza on a corporate pizza party
• Getting mad when seeing someone break spaghetti, despite no one actually caring
• The aversion of Onlyfans creators, despite avidly consuming similar forms of pornography
• People's negative reaction on food videos whenever they do not see gloves being used
• The persistence of cooking steak at a certain standard by people who don't really even cook at eat steak

Shawn: "Did you go to the company after-party last night? I heard Kylie was so drunk, she went up the stage and took off her top. Here, Jake sent me some pics. Look at those massive tits, man. Epic."
Mike: "Shit, really? I could've.. whatever, Kylie's a thot anyway. I would have went if it was Momoko again."
Shawn: "Dude, what's wrong with you guys. Momoko took on nine guys on the stage last year—from different departments, and only Kylie's seen being the thot?"
Mike: "Yeah, 'cause she's Japanese. Based."
Shawn: "Whatever man, you know you'd jump at the chance with Kylie. That's just the pineapple pizza effect."
