This is an aside but “trifecta but with four” actually has an awesome name: “Superfecta”!
One thing I discovered in the process is that the word water comes to english all the way from Proto Indo European. The word hydro, however, comes from ancient greek, which comes from the same PIE word for water.
From where I am, it is simply telly, because why not bastardise it some more while we are at it.
Sounds like someone made up the name to just sound better than trifecta. It's marketing speak.
Also, as the link says, it has been used to mean more than four. And other languages use their own equivalent of "quadfecta" instead.
Plus, I knew exactly what "quadfecta" meant, but would have no idea about "superfecta".
