It was apparently a Boston Pizza thing. Not hanging out that much in Canada, I'd never heard of Boston Pizza until recently. But it was obvious immediately that 1) While Boston Pizza seems to be based on Greek style pizza from my native New England, it has drifted enough that it's not really that similar, and 2) People generally find Boston Pizza to be poor based on the reviews.
Boston Pizza is to pizza what Cheesecake Factory is to cheesecake. It's not great pizza or even good pizza that they serve there (in addition to a million other things), but it's fine for what it is.
It's definitely not lutefisk. Silly list, a real demonstration of the limitations of crowdsourced, data generated content.
