"Blue sauce" is the east coast name for it. Out west and in the south it’s called "blue dressing", while in the Midwest it’s called "fresh blooble goo". There’s a map floating around somewhere that shows the different regional breakdowns.
There's actually a lot more than that.
And honestly, you could label most of metro areas as "blue sauce". Local dialects are dying out thanks to our modern world. Very sad to see.
I still laugh hysterically at this map from time to time. One of the all-time great posts.
