so don't i
What does so don't i mean?
One of the great brain-melters of New England English. Means the exact opposite of what it sounds like: 'so don't I' = 'so do I.' Used to enthusiastically agree. Linguists have written papers on it; Bostonians have been doing it since the Pilgrims and don't see what the fuss is about.
"I love a good roast beef from Kelly's. — So don't I, dude. Every Sunday."
Origin
Documented feature of Eastern New England English; the 'positive don't' construction has been studied since at least the 1970s.
