1st encounter with Hawaiian Pizza was in the late 1980s in a genuine mafia owned Italian Pizza place in town. [it was minor mafia family, petty stuff]
Anyway, it was ham and pineapple and I went through my WTF phase too.
Then I got used to it because a friend REALLY liked it and was paying so I ate it. Got used to it.
That said, this many years later, it’s not my first choice.
