Long ago, I knew someone who spent a weekend at one of the Hoi polloi mansions. It was an orgy of everything. He ended up asking what they did for something special.
I went into brain fog at that point.
"Hoi polloi" means "the masses; the common people." I've made the same mistake, more than once.
I think the expression you're thinking of is "hoity-toity."
The kids parents were always abroad. I feel luke they wanted attention looking back on it. There was also a gang of them that would smash car windows to steal Garfield window suction cup stuffed animals.
I knew a few of them.
