It’s a way overused meme by this point. I do find it to be more common online and in the states than anywhere else though. That’s the feeling I get at least.

Never encountered it in real life as far as I know. Sure, someone might not like pineapple on their pizza, but they haven’t gotten all ranty about it though.

For what it’s worth, it can be pretty nice. Especially on a spicier pizza with a bunch of chili and stuff on it to complement the sweetness.
